High temperature and erosion resistant centrifugal roller and manufacturing method thereof

High temperature and erosion resistant centrifugal roller and its manufacturing method

This invention discloses a centrifugal roller able to endure high temperature and brushing, which comprises the roller blank parent, protective layer on the outskirt of the parent. This invention also discloses a process method, which comprises the following steps: adopting general steel material to get roller parent; wielding the roller circle by use of manganese and steel wielding wire and carbon dioxide automatic wielding machine; drilling cool water into the inner hole of the roller to form the centrifugal manganese steel protective layer; then processing the centrifugal roller to get the needed centrifugal roller with protective layer.

Cutting system

The utility model discloses a cutting system for cut the rock wool board, cutting system includes rip cutting device and transverse cutter assembly, the rip cutting device includes a plurality of first saw bits, transverse cutter assembly includes the second saw bit, first saw bit with the second saw bit is discoid anodontia saw bit. To above -mentioned cutting system, because the dust that anodontia saw bit produced when the cutting is less, through further controlling the rotational speed, cutting system may not need to use the mechanism of gathering dust to reduce the power consumption in system's cost and the use, further reduced manufacturing cost again, in addition, the utility model provides a noise that cutting system produced in the course of the work is less to the production environment of workshop has been improved.

Anhydrous taphole clay and preparation method thereof

The invention provides anhydrous taphole clay. The anhydrous taphole clay is prepared by taking 20-24 parts by weight of high-aluminum aggregate, 23-24 parts by weight of corundum, 20-25 parts by weight of silicon carbide, 3-5 parts by weight of boron nitride, 6-8 parts by weight of asphalt and 8-10 parts by weight of coke as main raw materials and carrying out synergic coordination of additives namely 5-8 parts by weight of soft clay and 14-15 parts by weight of tar by virtue of burdening, mud grinding and molding. The invention also discloses a preparation method of the anhydrous taphole clay. The preparation method comprises the following steps of uniformly stirring the raw materials to obtain the mixed raw materials; transferring the mixed raw materials into a clay rolling machine and grinding for 40-50 minutes at 45-55 DEG C; transferring the ground clay material into a molding machine, extruding the clay at 55-65 DEG C clay-extruding opening, cutting the material block according to ...

Extrusion system and granulated wool baling press

The utility model provides an extrusion system and granulated wool baling press, above -mentioned extrusion system includes: extrude bin, actuating mechanism and push the baffle, the extrusion system still includes guiding mechanism, guiding mechanism fixes pushing the side of baffle, and pushing the baffle and removing the in -process, sliding connection extremely extrusion bin inner wall. Through guiding mechanism, pushing the baffle in -process that gos forward, the guiding mechanism of clearance department pushes the baffle with the prevention and takes place the incline to the assurance is pushed the baffle and is in the tram, and simultaneously through reducing the frictional resistance between guiding mechanism and the extrusion bin inner wall, pushing the baffle and can ging forward smoothly of guiding mechanism is installed in the assurance.

Cupola forehearth
