Abstract
A kiln structure of a well annealing furnace belongs to production facilities of metallurgy enterprises and comprises an outer wall, a partition wall and a bottom plate which are all made by concrete pouring. A heat insulation material and a heat-insulation blanket are arranged on the bottom plate, a heat insulation material, a heat-insulation blanket and a resistance zone are arranged on the inner side of the outer wall, and a heat insulation material, a heat-insulation blanket and a resistance zone are arranged on each side of the partition wall. The kiln structure is characterized in that both the outer wall and the partition wall are provided with pillars, guide posts are arranged the pillar side, and the guide posts on two sides of the partition wall are connected together. The kiln is divided into four chambers by the partition wall, the chambers can operate independently and simultaneously, the chambers are separated by the partition wall, and electric heating components for heating are distributed on the periphery of each chamber. One well is provided with a plurality of chambers, so that quick charging, interior slow cooling, quick heat insulation and quick annealing are achieved, cooling speed of hot rolled bars is slowed effectively, energy consumption is reduced, too fast cooling speed of collected products is avoided, and energy conservation and consumption reduction are achieved.
Description
Technical field
The utility model belongs to the production facility of smelter, is mainly used in the slow cooling and the annealing of chromium steel, T91 series bar, is specifically related to a kind of furnace kiln structure of well formula annealing furnace.
Background technology
Chromium steel, T91 series bar are mainly used in the processing of the supporting high-pressure seamless pipe in boiler factory, has good DEVELOPMENT PROSPECT, in producing chromium steel, T91 series bar heat treatment process, adopt existing well formula annealing furnace to heat-treat bar and exhibiting high surface crackle, inner crystalline substance occur and mass defect such as split, cause product not meet the demands.
Summary of the invention
For preventing that the mass defect that exhibiting high surface crackle, inner crystalline substance split from appearring in chromium steel, T91 series bar in process of cooling, the utility model provides a kind of furnace kiln structure of well formula annealing furnace.
The utility model comprises exterior wall, partition wall, the base plate of concrete depositing, be provided with lagging material, heat-insulation blanket above the base plate, the inboard of exterior wall is provided with lagging material, heat-insulation blanket, resistive band, the both sides of partition wall are equipped with lagging material, heat-insulation blanket, resistive band, it is characterized in that exterior wall, partition wall are equipped with pillar, the pillar side is provided with guide pillar, and the guide pillar of partition wall both sides links together.
The utility model comprises that also the bottom of each chamber all is provided with the material carrier platform of stacking bar.
Partition wall of the present utility model becomes four chambers at interval with stove, each chamber promptly can independently operate also and can operate simultaneously by several chambers, separated by partition wall between the chamber, be furnished with the electrical heating element of heating usefulness around each chamber, one well multi-cavity, realize quick shove charge, go into the stove slow cooling, insulation, short annealing (being no more than 5 minutes) fast from collecting shove charge, slow down the cooling rate of bar after the hot rolling effectively and reduced energy consumption, cooling rate is too fast after having avoided product to collect, and has also realized energy-saving and cost-reducing target simultaneously.
The utility model also has following advantage:
1, reduced the defective of chromium steel, T91 series bar: the T91 series bar surface crack after the slow cooling is reduced to 0.1 ﹪ by 13.6 ﹪.
2, reduced energy consumption: electric power consumption per ton steel is reduced to 127KW by 350kw, decreases by 64%.
3, shortened annealing time: per hundred tons of annealing times are reduced to 20h by 59h.
4, reduce the production logistics link: bar is collected the back before aligning from the heat material, reduces to 5 steps from 12 steps.
5, improved the anneal capability of bar: single stove can be annealed 300 tons; 600 tons of single stove slow cooling.
