Composite sliding plate brick pressing die and brick pressing process thereof

Abstract

The invention relates to a composite sliding plate brick pressing die and a brick pressing process thereof. The composite sliding plate brick pressing die comprises a floating upper die, a die box, a floating plate and a floating lower die; the floating lower die comprises a lower die holder and a lower die core fixed to the upper end of the lower die holder; a transverse through avoidance groove is formed in the middle of the lower die holder; the horizontal floating plate is slidably arranged in the avoidance groove in a sleeving manner; the lower portion of a vertical hollow jacking pipe is fixed to the middle of the floating plate, and a transverse through sliding groove is formed in the middle of the jacking pipe; the die box comprises a floating die frame and a supporting base fixed to the lower portion of the floating die frame; a core rod is vertically fixed in the middle of the supporting base; the supporting base is arranged in the sliding groove slidably; the floating die frame is vertically hollow, and the lower portion of the floating upper die, the lower die core and the upper portion of the lower die holder are all movably arranged on the inner periphery of the floating die frame in the sleeving mode; the core rod is movably arranged in the jacking pipe in the sleeving mode; the jacking pipe is movably arranged in the lower die holder and the lower die core in the sleeving mode; and a first driving mechanism is used for driving the floating lower die to move up and down, and a second driving mechanism is used for driving the floating plate to move up and down.

Description

technical field [0001] The invention relates to a composite sliding brick pressing mold and a brick pressing process thereof, belonging to the technical field of sliding brick production. Background technique [0002] With the increasingly severe refractory market, there is a shortage of non-renewable raw materials all over the world, and the supply of high-grade and high-performance raw materials is tight and the price is high. The whole piece of skateboard bricks uses uniform high-grade raw materials, and the cost pressure is getting bigger and bigger, making it difficult to maintain the good benefits and sustainable development of the enterprise. [0003] At the same time, as a functional refractory material for steelmaking, sliding bricks are used under harsh conditions. Therefore, the service life and safety of sliding bricks are important evaluation indicators. The forming process is a key process in the production and manufacture of skateboard bricks. The density and...

Problems solved by technology

In the traditional brick pressing mold, especially when producing sliding bricks with lower bosses (this kind of sliding bricks are mainly used in sliding nozzles with sub-female openings), it is necessary to pile more materials at the lower bosses, but at present It is only based on manual control, and most of them use the operation method of manual pressing and then stacking. First, the stacking needs to be manually controlled, and it is difficult to obtain accurate control. Second, the stacking of the lower boss is added in stages. The stress situation is different, and there will be problems of inconsistent density
