Description

Continous casting sprue is installed soon

The utility model is to install soon in a kind of metallurgical continuous casting mouth of a river.

At present in China metallurgical continuous casting system, the mouth of a river and ladle be one normally, because mouth of a river condition of work is abominable,, the mouth of a river in a single day damage shorter in its service life than ladle heat proof material, will be transported replacing, maintenance together with ladle, so not only time-consuming, and cause bigger waste, increased working strength of workers simultaneously.

The purpose of this utility model is that a kind of continous casting sprue of design is installed soon, in case the mouth of a river is damaged in using, just can directly change separately, can reduce the replacing number of times of ladle like this, reduce cost, alleviate labor strength, and can improve the recovery rate of iron and the billet quality of ladle in the continuous casting system.

The purpose of this utility model is achieved like this: the mouth of a river of metallurgical continuous casting is divided into filling pipe end, following mouth of a river two parts.At filling pipe end; the joint portion periphery at the following mouth of a river is provided with a cover by tank bracket; upper cover plate; clamping ring; main; secondary compression spring; install soon in the following mouth of a river that parts such as support spring leaf are formed; filling pipe end still is installed in the bottom of ladle; clamping ring is installed in the framework and by the main following back taper end of compressing spring and filling pipe end and clamps; in the cubic hole of frame center; its top cushion cap is in order to press the dress clamping ring; the bottom both end sides slips into track; then has installed in order to the spring leaf at the mouth of a river to be installed down in the stage casing on both sides, front and back; when the mouth of a river is damaged instantly; the standby following mouth of a river need only be placed on the track pin; thrust by hydraulic push rod; the standby following mouth of a river is pushed on the two row's spring leafs of front and back fast along slipping into track; the following mouth of a river that to damage is simultaneously released; just can extremely promptly more finish changing down the mouth of a river; and guarantee the sealing of faying face by the effect of main compression spring and spring leaf; in addition; also in upper cover plate, be provided with special-purpose duct and communicate, compress the effect of spring and reed and the effect that improves billet quality to play cooling cooling protection master with the compressed air and the argon system of peripheral hardware.

The fast installation of continous casting sprue that the utility model is carried is rational in infrastructure, safe and reliable, can reduce production costs and labour intensity has improved recovery rate of iron and billet quality again.Now fast installation is further described to continous casting sprue that the utility model is carried in conjunction with the accompanying drawings:
