Rotary tilting refining furnace
The rotary tilting refining furnace is mainly used for the pyrometallurgical refining of recycled metals (mostly used for impure copper). In order to improve the technical and economic comprehensive indicators of the tilting refining furnace, it is best to have a copper grade higher than 90% when entering the furnace. For raw materials with lower copper grades, it is best to first undergo pre-treatment in the blast furnace and blowing furnace before entering the tilting furnace.
The furnace body of the rotary furnace is installed on a rotating frame, which, under the action of a hydraulic cylinder, can tilt the furnace body within a certain angle range to achieve process actions such as feeding, melting, and dumping slag. At the same time, the furnace body can rotate around its axis under the action of the transmission mechanism; The rotary motion improves the heating efficiency of the furnace and is of great significance for the overheating of the molten metal.
When melting metal in this furnace, a certain amount of slag forming agent needs to be added. The molten slag forming agent and slag liquid have a protective effect on solid and liquid metals, which can prevent metal oxidation
The burning loss rate of elements such as silicon and manganese in a rotary cupola is equivalent to that of a coke burning cupola. The content of carbon elements in the rotary furnace is decreasing, so it is necessary to add a certain amount of carburizing agent ( graphite) to the furnace material.

Lead liquid mixer
During the impurity removal process of crude lead refining, it is necessary to put the refining auxiliary materials into a lead pot containing liquid lead liquid, and use a mixer to stir the lead liquid to promote contact between the auxiliary materials and the lead liquid. The conventional stirring method is to install vertical blades at the bottom of the stirring shaft, and place the stirring shaft at the center of the lead pot for stirring.
Lead pot cover
The cover plate is composed of 10mm thick steel plates
5) Furnace insulation cover (movable): outer layer 6mm, inner layer 60mm
Heat insulation (the furnace insulation cover is formed by one-time stamping,
Manual lifting, capable of 360 degree rotation)
The pouring system is composed of a gate cup, a straight gate, a horizontal gate, and an inner gate. It is a channel opened inside the mold to introduce liquid metal into the mold cavity.
The function of the pouring system is to control the speed of metal liquid filling the mold and the time required to fill the mold; Ensure that the metal liquid enters the mold smoothly, avoiding turbulence and erosion of the mold; Prevent slag and other inclusions from entering the mold cavity; During pouring, do not involve gas and try to ensure that the casting cools down in accordance with the principle of sequential solidification.
The pouring system includes:
1. Pouring cup. The metal liquid poured into the ladle, also known as the external gate
2. Straight gate. Connect the outer gate and the transverse gate to introduce molten metal from the outside of the mold into the inside of the mold
3. Horizontal gate. Connect the straight gate and distribute the metal flow from the straight gate.
4. Inner gate. Connect the transverse gate and inject molten metal into the mold cavity.
The function of the pouring cup is to guide the liquid metal poured from the ladle into the straight gate. The gate cup of small castings is mostly funnel-shaped, and the diameter of the upper gate should be more than twice that of the straight gate, and it is generally made directly on the mold during molding.
Slag casting machine
The slag casting machine is used for casting copper slag or lead slag. Copper slag is mainly used for casting converter slag, and lead slag is mainly high lead slag discharged from the casting oxidation furnace. Workflow: After the slag flows out of the furnace, it flows into the slag mold of the slag casting machine through a chute from the casting point. The slag mold is fixed on the chain conveyor, and the slag inside the slag mold is gradually transported from the casting point to the slag ingot outlet through the air and water cooling areas by the chain conveyor on the slag casting machine, and then discharged.
