Embodiment 1

[0022] The raw and auxiliary materials for mold casting include mold powder, heating agent, and carbonized rice husks, which have passed the factory acceptance inspection and are packaged according to specifications. In the baking room, the general temperature is controlled at 50-70°C, and the baking is good. The time to send to the pouring station is controlled within 30 minutes before pouring steel. Special device feeding hopper.

[0023] The adding method is as follows: For the quadrilateral ingot type, the ingot weight is 2-5.5t, and the steel type is stainless steel, die steel, and carbon bonded steel. When the height of the liquid steel level and the thickness of the mold slag reach the observation position, immediately open the special device. Add heating agent and carbonized rice husk or thermal insulation agent to the switch, and control the flow rate at 2.5-3.0Kg / S to ensure that the steel ingot is poured full.

[0024] The device used in the method of the present i...

Embodiment 2

[0031] For polygonal ingots, ingot weight 2-40t, all special steel types, when the liquid steel level reaches the observation position, immediately turn on the flow rate switch of the special device to add heating agent and carbonized chaff, and control the flow rate to 3.0-3.5Kg / S , to ensure that the steel ingot is poured full.

Embodiment 3

[0033] For the four-sided ingot type, the ingot weight is 0.8-1.4t, and the mold steel is used. When the liquid steel level reaches the observation position, immediately turn on the flow rate switch of the special device to add heating agent and carbonized chaff. The flow rate is controlled at 2.0-2.5Kg / S. Make sure that the ingot is poured full.

Abstract

The invention discloses an adding device for die casting auxiliary materials and a adding method for the adding device, and belongs to the technical field of designing and manufacturing of metallurgical production auxiliary equipment. The adding device for the die casting auxiliary materials and the adding method for the adding device have the advantages of being convenient to operate and capable of remarkably improving the operating environment of an operator. The adding device comprises an auxiliary material containing cavity and an auxiliary material adding control system; an auxiliary material conveying channel is arranged at the bottom of the auxiliary material containing cavity; and the auxiliary material adding control system is arranged on the auxiliary material conveying channel. The adding method comprises the steps that the adding device filled with the die casting auxiliary materials is lifted right above a casting die through lifting equipment, then the auxiliary material conveying channel at the bottom of the auxiliary material containing cavity of the adding device is opened, and the die casting auxiliary materials which are stored in the auxiliary material containing cavity in advance are added to the surface of molten steel.

Description

technical field [0001] The invention relates to a feeding device, in particular to a feeding device for mold casting auxiliary materials, and belongs to the technical field of design and manufacture of metallurgical production auxiliary equipment. The invention also relates to a method for adding auxiliary materials for molded ingots by using the adding device. Background technique [0002] The auxiliary materials that need to be added in the process of special steel mold casting mainly include mold slag, heating agent and heat preservation agent. At present, the addition of heating agent and heat preservation agent in the mold casting process mainly depends on manually standing on the mold casting workbench and throwing or throwing them into the mold. throw. Dust splashes during the adding process, the working environment is harsh, and sometimes the throwing will lose its accuracy, and the heating agent and heat preservation agent cannot be fully and evenly covered on the ...
