Abstract
The invention relates to a pipe fitting charging method and in particular relates to a charging method applied to pipe fitting vacuum heat treatment. The charging method provided by the invention is characterized in that pipe fittings are mounted in a charging rack in hearth of a vacuum heating furnace, heating elements are arranged around the charging rack; the charging rack is of a rectangular structure, the charging rack is divided into four rectangular compartments which are the same, the same quantity of pipe fittings are placed in each rectangular compartment, the pipe fittings in each rectangular compartment are degressively stacked and put one by one from bottom to top, and a shape formed by the end parts of pipe fittings is an isosceles trapezoid in a forward-looking direction after the pipe fittings in each rectangular compartment are put. By adopting the charging method provided by the invention, time for causing the pipe fitting at the middle part (the coldest pipe fitting) and the pipe fitting at the periphery (the hottest pipe fitting) to be the required temperature is greatly shortened, heating uniformity is good, efficiency is high, and cost for energy consumption is greatly reduced.
Description
Technical field
The present invention relates to a kind of loading method of pipe fitting, specifically a kind of loading method of pipe fitting vacuum heat treatment.
Background technology
pipe fitting is when carrying out vacuum oven thermal treatment, pipe fitting need to be put into the charging skid that is arranged in the vacuum furnace burner hearth, charging skid is generally rectangular configuration, the charging method of traditional pipe fitting vacuum heat treatment as shown in Figure 1, pipe fitting 1 is put into the charging skid 2 that is arranged in the vacuum furnace burner hearth, charging skid 2 surroundings are the heating unit 4 that is fixed on vacuum hearth inwall 3, after installing, pipe fitting 1 sees that from main apparent direction the shape that each pipe fitting end forms is hexagon, such loading method advantage is that batch is large, main drawback is the poor synchronization of pipe fitting (the coldest pipe) with pipe fitting (heat pipe) the arrival preset temperature of periphery at middle part, the thermal treatment homogeneity is controlled undesirable, and thermal treatment temperature-rise period and temperature-fall period are slow, the whole heat treatment process cycle is long, power consumption is large, cost is high.
Summary of the invention
Technical problem to be solved by this invention is, overcome the shortcoming of prior art, a kind of loading method of pipe fitting vacuum heat treatment is provided, the pipe fitting (heat pipe) of the pipe fitting (the coldest pipe) in the middle part of can greatly shortening and periphery reaches the temperature required time, being heated evenly property is good, efficient is high, has greatly lowered energy consumption cost.
The technical scheme that the present invention solves above technical problem is:
A kind of loading method of pipe fitting vacuum heat treatment, pipe fitting is put into the charging skid that is arranged in the vacuum furnace burner hearth, the charging skid surrounding is provided with heating unit, charging skid is rectangular configuration, charging skid is divided into four little lattice of identical rectangle, the pipe fitting that the quantity of packing in the little lattice of each rectangle equates, pipe fitting from bottom to up by root stacking the putting of successively decreasing, sees that from main apparent direction the shape that each pipe fitting end forms is isosceles trapezoid after pipe fitting is well placed in the little lattice of each rectangle in the little lattice of each rectangle.
for those skilled in the art, as far as possible large in order to pursue batch, generally all adopt the charging method (being the charging method in documents) of " hexagon ", the applicant finds by research, above traditional charging method can make the pipe fitting at middle part colder, peripheral pipe fitting is warmmer, in order to solve this technical problem, the applicant's further investigation, bin is divided into four lattice, like this, pipe fitting residing in vacuum oven " environment " symmetry in arbitrary grid, therefore, in heat treatment process, only needing that the pipe in arbitrary grid is carried out monitoring temperature gets final product, the number of tubes of each little lattice is relatively less, heat transfer efficiency improves, can solve largely the pipe fitting inhomogeneous technical problem of being heated, but in each grid, the pipe fitting stack manner is different, the technique effect that obtains is also different, for this reason, the applicant is further further investigation again, finally draw the stack manner of isosceles trapezoid, the stack manner of isosceles trapezoid in heat treatment process, the first, can reduce the time that " the coldest pipe " and " heat pipe " rise to design temperature, the second, the temperature difference in insulating process between " the coldest pipe " and " heat pipe " further reduces, can be near 0 temperature difference, the 3rd, in temperature-fall period, due to the raising of heat transfer efficiency, so the cooling rate of material promotes greatly.
The technical scheme that the present invention further limits is:
The loading method of aforesaid pipe fitting vacuum heat treatment, charging skid are square, and charging skid is divided into four identical square little lattice.
The loading method of aforesaid pipe fitting vacuum heat treatment is positioned at uppermost pipe fitting and is set to two in the little lattice of each rectangle.
The present invention is divided into four little lattice with square bin, puts pipe fitting according to trapezoidal stacking mode in each grid; This windrow mode is by disperseing windrow, each regional pipe fitting quantity is equated, and material symmetry in whole vacuum oven is placed, make the interior pipe " environment " of living in whole vacuum oven of four lattices consistent, be heated evenly when thermal treatment, and in temperature-rise period, greatly shortened " the coldest pipe " and " heat pipe " and reached the temperature required time, being heated evenly property is good, efficient is high, has greatly lowered energy consumption cost.

Embodiment
the present embodiment provides a kind of loading method of pipe fitting vacuum heat treatment, as shown in Figure 2, pipe fitting 1 is put into the charging skid 2 that is arranged in the vacuum furnace burner hearth, charging skid 2 surroundings are the heating unit 4 that is fixed on vacuum hearth inwall 3, charging skid 2 is square, foursquare charging skid 2 is divided into four identical square little lattice 5, material supplier all set after, swing in successively cleaning straight pipe later in bin, the pipe fitting 1 that the quantity of packing in each square little lattice 5 equates, pipe fitting 1 in each square little lattice 5 from bottom to up by root stacking the putting of successively decreasing, the superiors arrange two pipe fittings, the width of undermost pipe fitting quantity lattice 5 little of square is decided, after being well placed, the interior pipe fitting of each square little lattice 5 sees that from main apparent direction the shape that each pipe fitting end forms is isosceles trapezoid, after the whole stackings of four lattice are complete, bin pushed in stove heat-treat.
The present embodiment can effectively improve thermal conductivity, has accelerated the coldest and heat pipe and has risen to the required time of holding temperature.Simultaneously, because being has divided equally former bin, so each little lattice residing " environment " are symmetrical consistent, and therefore the homogeneity when whole pipe fitting thermal treatment is provided when monitoring pipe fitting temperature homogeneity, only needs carry out the monitoring of temperature to the pipe in arbitrary grid; Simultaneously, because material divides four stackings, discharge furnace inner space, effectively improved thermal conductivity, made the cooling of heat treatment process more efficient.The present embodiment can improve the heat treated effect of vacuum oven and efficient greatly, reduces simultaneously energy consumption cost.
In addition to the implementation, the present invention can also have other embodiments.All employings are equal to the technical scheme of replacement or equivalent transformation formation, all drop on the protection domain of requirement of the present invention.
