The tapping slide rail of the steel-pushing type heating furnace comprises a furnace bottom water pipe, a first tapping slide rail, a second tapping slide rail, a heat-resisting slide rail, a tapping platform and the steel tapping spout, wherein the heat-resisting slide rail, the tapping platform and the steel tapping spout are located above the furnace bottom water pipe and are arranged sequentially from inside to outside, and the steel tapping spout is made of steel tapping spout bricks; the surface of the heat-resisting slide rail is higher than the upper surface of the steel tapping spout; the lower ends of the first and second tapping slide rails are connected with the furnace bottom water pipe; the upper surface of the second tapping slide rail inclines downwards from the inside to the outside; the second tapping slide rail is joined with bricks of the steel tapping spout; the upper surface of the second tapping slide rail forms the tapping platform; the upper surface of the first tapping slide rail inclines downwards from the inside to the outside; and the two ends of the first tapping slide rail are joined with the second tapping slide rail and the heat-resisting slide rail respectively and are in smooth transition. The tapping slide rail of the steel-pushing type heating furnace can be applied to design of steel-pushing type heating furnaces or reconstruction of existing steel-pushing type heating furnaces.
Description
Technical field
The present invention relates to billet heating furnace field, particularly relate to a kind of pusher-type heating-furnace steel-tapping slide rail.
Background technology
At present, the running condition of pusher-type furnace is, after qualified steel billet enters process furnace, through heating one section, heating two sections and soaking zone arrive tapping platform along heat-resistant slide-rail, then rolls into tapping spout, release tapping with pusher.
Tapping platform and heat-resistant slide-rail are taken by heat resisting brick and are built into, and during design, floor tube has difference of altitude, causes heat-resistant slide-rail to be difficult to build smoothly, and heat-resistant slide-rail is difficult to seamlessly transit with tapping platform.Steel billet is in the process of heating, propelling, and easily bend, bending part is often suspended on heat resisting brick, occurs quick-fried steel, pushes away the phenomenons such as motionless.And often the heat resisting brick on outfeed platforms is hung bad, have a strong impact on carrying out smoothly of production.
Summary of the invention
The technical problem to be solved in the present invention is: provide a kind of steel billet that enables smoothly by the pusher-type heating-furnace steel-tapping slide rail passed in process furnace in tapping spout.
In order to solve the problem, the technical scheme adopted is: pusher-type heating-furnace steel-tapping slide rail comprises floor tube and to be positioned at above floor tube and the heat-resistant slide-rail set gradually from inside to outside, tapping platform and tapping spout, and tapping spout is by the brick one-tenth of tapping spout; Heat-resistant slide-rail surface is higher than tapping spout upper surface; Pusher-type heating-furnace steel-tapping slide rail also comprises the first tapping slide rail and the second tapping slide rail be made up of ZGCr25Ni20Si2; First tapping slide rail is all connected with floor tube with the lower end of the second tapping slide rail; Second tapping slide rail upper surface is downward-sloping from inside to outside, and the second tapping slide rail outer end is connected with tapping spout brick, and the second tapping slide rail upper surface forms tapping platform; First tapping slide rail upper surface is downward-sloping from inside to outside, and tap with second respectively slide rail and heat-resistant slide-rail of the outer end of the first tapping slide rail and the inner is connected and seamlessly transits.
Further: the shape of the first tapping slide rail lower surface length direction is consistent with floor tube shape.
Further: the shape of the first tapping slide rail and the second tapping slide rail lower surface width is arc and radius mates with floor tube radius.
Further: the first tapping slide rail and the second tapping slide rail are all welded with floor tube by stainless steel electrode.
The invention has the beneficial effects as follows: all seamlessly transitting to supporting the tapping slide rail of steel billet movement and this tapping slide rail and tapping spout and heat-resistant slide-rail between tapping spout in process furnace, avoiding in steel billet moving process and occurring bite.Tapping platform be can't help heat resisting brick and is set up formation, avoids occurring that the steel billet that the heat resisting brick of tapping platform causes pushes away motionless phenomenon.
Accompanying drawing illustrates:
Fig. 1 is pusher-type heating-furnace steel-tapping slide rail side-view;
Fig. 2 is pusher-type heating-furnace steel-tapping slide rail vertical view;
Be labeled as in figure: heat-resistant slide-rail 1, first tapping slide rail 2, second tapping slide rail 3, tapping platform 4, tapping spout brick 5, tapping spout 6, floor tube 7.
Embodiment
Below in conjunction with the drawings and specific embodiments, the present invention is further described.
As depicted in figs. 1 and 2, pusher-type heating-furnace steel-tapping slide rail comprises floor tube 7 and to be positioned at above floor tube 7 and the heat-resistant slide-rail 1 set gradually from inside to outside, tapping platform 4 and tapping spout 6, and tapping spout 6 is built into by tapping spout brick 5; Heat-resistant slide-rail 1 upper surface is higher than tapping spout 6 upper surface; Pusher-type heating-furnace steel-tapping slide rail also comprises the first tapping slide rail 2 and the second tapping slide rail 3 be made up of ZGCr25Ni20Si2; First tapping slide rail 2 is all connected with floor tube 7 with the lower end of the second tapping slide rail 3; Second tapping slide rail 3 upper surface is downward-sloping from inside to outside, and the second tapping slide rail 3 outer end is connected with tapping spout brick 5, and the second tapping slide rail 3 upper surface forms tapping platform 4; First tapping slide rail 2 upper surface is downward-sloping from inside to outside, and tap with second respectively slide rail 3 and heat-resistant slide-rail 1 of the outer end of the first tapping slide rail 2 and the inner is connected and seamlessly transits.Above-mentioned in the description in direction, " interior " refers to inside heating furnace, and " outward " refers to that process furnace is outside.
First tapping slide rail 2 instead of close tapping platform 4 part of original heat-resistant slide-rail 1.The first tapping slide rail 2 that steel are made easily adapts to the difference of altitude of floor tube 7, makes the first tapping slide rail 2 upper surface level and smooth and seamlessly transits with the inside and outside parts be connected, avoiding the bite in steel billet moving process.
Second tapping slide rail 3 instead of and is originally built into tapping platform 4 by heat resisting brick, avoids occurring that the steel billet that causes of heat resisting brick of tapping platform 4 pushes away motionless phenomenon.
ZGCr25Ni20Si2 material wear-resistant performance is good, can delay steel billet and first slide rail 2 and second slide rail 3 of tapping of tapping and to rub the wearing and tearing caused, make the first tapping slide rail 2 and the second tapping slide rail 3 life-span longer.
In order to ensure that the first tapping slide rail 2 is connected well with floor tube 7 with the second tapping slide rail 3, following measures can be taked: the shape of (one) first tapping slide rail 2 lower surface length direction is consistent with floor tube 7 shape.The shape of (two) first tapping slide rails 2 and the second tapping slide rail 3 lower surface width is arc and radius mates with floor tube 7 radius.
First tapping slide rail 2 and the second tapping slide rail 3 and floor tube 7 specifically mode of connection are recommended as: the first slide rail 2 and second slide rail 3 of tapping of tapping all is welded with floor tube 7 by stainless steel electrode.
The present invention can be applicable in design of Pusher-type Furnace, also can be used for transforming existing pusher-type furnace.
