Description

Bottom filling ladle

Technical field

Bottom filling ladle described in the utility model, it is related to a kind of metallurgy industry special equipment, specially bottom is cast Formula ladle.

Background technology

The casting mode of the ladle used in current industry is divided into tilt bed, stopper rod type, slide gate nozzle formula etc.；According to Different situations and different modes are needed to use to cast, but the problem of the problem of this is different, specific to be all present as follows for each way：

1st, tilt bed：Delivery port can not operation under nearly zero elevation again, difference in height generates the drop gravity of molten steel, causes to fall The molten steel entered in mould flashes, and causes the danger of personal injury to operating personnel, and the problems such as equipment damage；

2nd, stopper rod type：The carbon-point of consent for a long time and steel contacts, can change in steel drum, the phosphorus content of molten steel, into Product quality declines；

3rd, slide gate nozzle formula：Because the low secondary formed using elastic bearing sliding plate brick realizes that reciprocal planar movement reaches out Open and close bottom of the barrel delivery port and complete casting work.In this process there is following point in sliding plate brick：

A, the Flexible element majorities for forcing in skateboarding brick are the upper and lower flexible of fixation.So the brick upper and lower surface is equal The pressure of action and reaction is born, and it is the brick both surface friction power sum to drive the pulling force of the brick planar movement, thrust.

B, changing the sliding plate brick can only be carried out in the state of bucket is without molten steel.

C, the sliding plate brick majority of the low secondary composition is the delivery port of a bore, and service efficiency is low.
