A method for baking ladles during silicon smelting

Abstract

The invention discloses a roasting method of ladle in silicon smelting process. The roasting method comprises the following steps: S1. constructing a special tower body for roasting the ladle in a silicon smelting and pouring place, wherein the height of the tower body is 9.6 meters, the largest width bottom is 8.4 meters, the narrowest width of the upper end is 6.3 meters, three sides of the tower body are constructed, another side is hinged with an encapsulation plate, the top of the tower body is closed, two partition plates and four baffles are arranged, each partition plate is provided with a plurality of first openings at equal intervals, the width of each first opening is 175mm-265mm, the baffle is 3.6 meters high, and a plurality of second openings are formed in each baffle. The roasting method facilitates the cyclic utilization of energy resources, the sustainable development and green production can be realized, and the generation of waste gas and dust in combustion can be prevented from polluting the environment, so that the environment protection is facilitated, the roasting time is greatly shortened, the roasting speed is quickened, the roasting efficiency is efficiently improved, and the labor intensity of working staffs can be effectively lowered.

Description

technical field

[0001] The invention relates to the technical field of silicon smelting equipment, in particular to a method for baking ladles during the silicon smelting process. Background technique

[0002] Vacuum ladle is a kind of turnover equipment commonly used in the metallurgical industry. It is a relatively large airtight container made of steel shell lined with refractory materials. A certain vacuum degree is generated in the ladle by the negative pressure generating device on it, so as to Extract the smelted liquid silicon, magnesium and other metals from the electrolytic tank and transfer them to other places. The vacuum bag has a cover to generate a vacuum, which is convenient for absorbing the liquid metal in the electrolytic tank. It has both suction and transfer functions. And the open bag only has the transfer function. Vacuum ladle only produces a small negative pressure when absorbing liquid metal, and it is in a state of normal pressure most of the time...
