Abstract

The invention relates to the technical field of refractory brick production, in particular to a refractory brick production process, which comprises the following steps of firstly, putting refractory brick raw materials into a refractory brick production device; and secondly, extruding the raw materials of the refractory bricks in the refractory brick production device up and down by using the refractory brick production device to form the raw materials of the refractory bricks into the refractory bricks. The buffer discharging mechanism can absorb impact generated by rigid thrust along with the movement of the pushing frame in the direction of the discharging conveyor, impact caused by collision on the edge of the refractory brick with complete structure due to overlarge thrust is avoided, meanwhile, the buffer rubber pad receives the reaction force of the refractory brick and can push the buffer baffle and the two buffer sliding rods to axially slide along the two linear bearings, so that the two first-stage buffer springs are compressed, the reverse impact force of the refractory brick on the buffer rubber pad is further absorbed, and impact damage to the refractory brick when pushed can be effectively reduced due to the double buffer effect.

Background The refractory material is used as a core base material in the fields of metallurgy, building materials, chemical industry, electric power and other high-temperature industries, wherein the refractory brick is widely applied to lining construction of various industrial kilns and heating devices by virtue of excellent refractory performance, high-temperature structural strength and chemical stability. At present, the main stream production process of refractory bricks adopts a powder compression molding method, and the main process comprises the steps of filling raw materials (refractory aggregate, powder, binding agent and the like) into a die cavity of a press die by a material distribution device after metering, mixing and ageing, pressing the raw materials into compact green bricks by a hydraulic press or a friction press under high pressure, ejecting the green bricks from the die cavity by an ejection mechanism, and finally pushing the green bricks to a conveying line or a transfer platform by a pushing mechanism to enter the following drying and sintering processes. The pushing mechanism of the existing refractory brick pressing equipment generally adopts a structure form of a rigid pushing plate and linear driving (an air cylinder/a hydraulic cylinder/an electric push rod), when the ejection mechanism ejects the green brick from the die completely and enables the green brick to be placed on a working table surface stably, the pushing plate of the pushing mechanism stretches out rapidly along the horizontal direction under the action of a driving source and directly contacts with the end face of the green brick, the green brick is pushed out of the working area of the press by the rigid pushing force to realize the connection of demoulding and transferring, For example, a chinese patent with the application number 202511434601.8 discloses a pressing device for producing refractory bricks, in which in the process of blanking, a push plate is in hard contact with a green brick, no buffer exists, instant impact force exists at the moment of push starting, as the particles in the green brick are bonded by a small amount of bonding agent, the overall anti-fracture and impact strength is extremely low, and the instant impact stress is easy to generate microcracks in the green brick, even form penetrability cracks, and break directly in severe cases.
