Abstract
A kind of furnace bottom refractory brick suitable for pusher-type furnace belongs to converter technical field of refractory materials, for make steel billet be evenly heated with it is easy to remove.Its technical solution is：Its lower half portion is upright cuboid or square, top half is hemisphere, the upper top surface of cuboid and bottom surface are square, four sides of cuboid are rectangle, hemispheroidal circumferential edges are connected with the upper top edge of cuboid, the hemisphere of top half and the cuboid of lower half portion are structure as a whole, and there is wear-resistant coating on the hemisphere surface of top half.The utility model is simple in structure, be easy to make, conveniently pushes away steel operation, steel billet uses point contact with furnace bottom refractory brick surface, and the wear-resistant coating that furnace bottom refractory brick top surface has friction coefficient very low, the temperature difference of upper and lower surface during heating steel billet can be eliminated and reduce furnace bottom refractory brick damaged surfaces, improve the service life of furnace bottom refractory brick, the tapping difficulty for reducing pusher-type furnace, improves the quality of product.
Description
Technical field
The utility model is related to a kind of pusher-type furnace furnace bottom refractory brick for being evenly heated and moving convenient for steel billet, belong to
Converter technical field of refractory materials.
Background technology
Pusher-type furnace is the capital equipment of steel material heat treatment, simple in structure, easy to operate, but steel billet exists
It needs to be pushed into and pull out heating furnace when heating, it will be with the refractory brick of flat Bottom of Heating Furnace during steel billet push-in and pull-out
Abutting contact causes steel billet upper and lower surface non-uniform temperature, the steel billet frictional force when being moved in furnace bottom refractory brick plane big, push
And the problems such as tapping difficulty.For especially heating furnace after use after a period of time, furnace bottom refractory brick plane becomes concave-convex because of abrasion
Injustice is easy to be stuck when not only steel billet is tapped, and since tapping overlong time can cause steel billet temperature drop apparent, influences steel billet
Processing and production, reduce product quality, therefore take measures to reduce steel billet with the contact of furnace bottom refractory brick and friction to be very
It is necessary.
Utility model content
The technical problem to be solved by the utility model is to provide a kind of furnace bottom refractory brick suitable for pusher-type furnace,
This furnace bottom refractory brick can make the heating of steel billet upper and lower surface more uniform, reduce furnace bottom refractory brick damaged surfaces, keep tapping simple
It is single convenient, improve the quality of product.
Solving the technical solution of above-mentioned technical problem is：
A kind of furnace bottom refractory brick suitable for pusher-type furnace, it is made of top half and lower half portion, lower half
It is divided into upright cuboid or square, top half is hemisphere, and the upper top surface of cuboid and bottom surface are square, rectangular
Four sides of body are rectangle, and hemispheroidal circumferential edges are connected with the upper top edge of cuboid, the half of top half
Sphere and the cuboid of lower half portion are structure as a whole.
There is wear-resisting painting on the hemisphere surface of the above-mentioned furnace bottom refractory brick suitable for pusher-type furnace, the top half
Layer, the thickness of wear-resistant coating are 0.2 2mm, and the friction coefficient of wear-resistant coating and steel billet is 0.01 0.1.
The utility model has the beneficial effects that：
The utility model improves the furnace bottom refractory brick of pusher-type furnace, and the top half of refractory brick is hemisphere
Shape simultaneously has wear-resistant coating, steel billet only dome point contact with furnace bottom refractory brick top half so that steel billet upper and lower surface by
Thermal change obtains more uniform；Simultaneously because the contact surface of steel billet and furnace bottom refractory brick reduces, and the wear-resisting painting of furnace bottom refractory brick top surface
Layer is very low with the friction coefficient of steel billet, substantially reduces the frictional force between steel billet and furnace bottom refractory brick, not only can be very convenient
Ground pushes steel billet into heating furnace, and significantly improves the service life of furnace bottom refractory brick.
The utility model is simple in structure, is easy to make, convenient for pushing away steel operation, and steel billet is connect with furnace bottom refractory brick surface using point
It touches, the temperature difference of upper and lower surface during heating steel billet can be eliminated, reduce furnace bottom refractory brick damaged surfaces, hence it is evident that reduce and push away steel
The tapping difficulty of formula heating furnace, improves the quality of product, has significant economic benefit.
Description of the drawings
Fig. 1 is the structural schematic diagram of the utility model；
Fig. 2 is the vertical view that pusher-type furnace furnace bottom installs the utility model.
It is marked in figure as follows：Cuboid 1, hemisphere 2.
Specific implementation mode
The utility model is made of top half and lower half portion.
It is shown in figure, lower half portion is upright cuboid 1 or square, and the upper top surface of cuboid 1 and bottom surface are just
Rectangular, four sides of cuboid 1 are rectangle or square.
It is shown in figure, top half is hemisphere 2, can also be spheroid or other convex shapes, the circumference of hemisphere 2
Edge is connected with the upper top edge of cuboid 1, and the hemisphere 2 of top half and the cuboid 1 of lower half portion are integrated knot
Structure.
It is shown in figure, there is smooth wear-resistant coating on 2 surface of hemisphere of top half, and the thickness of wear-resistant coating is 0.2
The friction coefficient of 2mm, wear-resistant coating and steel billet is 0.01 0.1.
It is shown in figure, the utility model is laid on the furnace bottom of pusher-type furnace when in use, and polylith refractory brick is in furnace bottom
Close-packed arrays, hemisphere 2 form evenly spaced protrusion in furnace bottom.By steel billet be pushed into pusher-type furnace when, steel billet only with it is resistance to
The apexes contact of the hemisphere 2 of firebrick top half.
Apexes contact due to steel billet with the hemisphere 2 of refractory brick top half, makes the top half of adjacent refractory brick
There is larger gap between hemisphere 2, therefore the lower surface of steel billet can be heated by furnace high-temperature so that steel billet upper surface is under
Surface is uniformly heated.Simultaneously as there are smooth wear-resistant coating, wear-resisting painting in 2 surface of hemisphere of refractory brick top half
Layer is very low with the friction coefficient of steel billet, not only can easily push steel billet into heating furnace, and substantially reduce steel billet
With the frictional force between furnace bottom refractory brick, reduces furnace bottom refractory brick damaged surfaces, improve the service life of furnace bottom refractory brick.
