D301 Converter Slap-blcok Mechanism

 D301 Converter slap-blcok mechanism
 
Product Summary
 
With the development of technology in the iron and steel enterprise, especially for the production of Clean steel, High-Quality Steel, the steelmaking process are improved continuously so as to resolve the factors which affect the steel. For now, during the steelmaking converter, With the increase of the converter lining life£¬irregular changes of shape of steel tapping hole in furnace, it decrease the effect of slag-stooping and result in the steel slag enter into ladle and cause damage to the out -of -furnace refining process technology, it is difficult to control  the steel elements in the ideal scope because of the rephosphorization and resulfurization, all above become the obstacles of smelting good-quality steel for the steel converter. So, our company research and develop the taking slide plate device in the steel tapping hole of converter and the open and close of the slide plate which are driven by mechanism shows an evident effect on slag-blocked tapping, it can meet the request of little or no slag taping of steel converter.
 
 
Component and working principles of mechanism
 
D301 Converter slap-blcok mechanism consist of ground work and junction plate,  Switch frame, fixed mould, spring components and so on. Raised slide plate lock is fixed in the mould, lower slide plate and lower nozzle are fixed in the slide mould. Slide mould frame can be movable through the sideway in the switch frame and the movable interface can establish constant uniform interface pressure by spring components.  Power producer hydraulic cylinder drives advance and return movement of the slide mould through the driving components and it also can control the molten steel and block the slag.

Slide nozzle is composed of upper slide plate, lower slide plate and lower nozzle. So we select alkalescent and burnt slide plate as material of slide plate combining with the characteristic of converter steel tapping and refractory melting loss from steel slag to satisfy the request of the heat-shocking stability£¬slag corrosion resistance and flushing resistance. There never appears nipped steel, galling, board wear and chambering phenomenon. According to the condition of the steel plant, it can be used for about 15-20 times. It can meet the needs of steel-making with its stable and reliable performance.
