Smelting Furnace Charging Process

Smelting Furnace Charging Process

In order to ensure the quality of the metal alloy ingots and prolong the service life of the melting furnace as much as possible, all preparations for the melting furnace must be done in the actual production process, including furnace loading, oven drying, furnace washing, furnace cleaning, stirring, and slag removal. and refining operations.

1. Furnace installation

During smelting, the order and method of charging the charge are related to the smelting time, metal burning loss, energy consumption, and also affect the quality of the melt and the service life of the furnace. The principles of furnace loading are as follows:

(1) The charging sequence should be reasonable, and the melting speed of the material should also be considered according to the nature and state of the charged charge;

(2) Small or thin scraps are loaded first, aluminum ingots and large pieces are loaded in the middle, and intermediate alloys are loaded last;

(3) The master alloy with low melting point and easy oxidation is installed in the lower layer, and the master alloy with high melting point is installed on the top. The high temperature in the upper part of the furnace is conducive to full melting and diffusion, so that the distribution of the master alloy is uniform, which is conducive to composition control;

(4) The added charge is evenly distributed in the molten pool, and the melting speed is consistent to prevent overheating of the metal due to overweight;

(5) The charge is fed into the furnace at one time as much as possible, and multiple additions will increase the inhalation of the melt;

(6) When charging the electric furnace, pay attention to the safe distance between the highest point of the charge and the heater on the top of the furnace to prevent electric shock and damage to the heating facilities.

Structural design of all-fiber trolley resistance furnace

 This paper focuses on the structural design of a full-fiber trolley-type resistance furnace. It uses high-aluminum full-fiber modules, CrMn resistance strips and fiber seals to replace the traditional brick kiln-type resistance furnace structure. It saves 30% of the overall power and is energy-saving, environmentally friendly, and convenient. Applicable, safe and reliable features. Research on vacuum brazing technology of dissimilar metals This trolley furnace is mainly used for tempering and welding annealing of large automobile forgings such as 45, 50, 55, 12Mn2VB, 40Cr, 42CrMo, 32MnSiVS5 and other steels. It is also used for low-temperature processing of carbon structural steel, alloy steel, mold steel and other products. Effect of filler metal on vacuum brazing of cemented carbide and steel In the tempering treatment, the parts are heated to the process temperature in the furnace and then insulated, and then come out of the furnace to be air-cooled to complete the

Trolley oven use

 It is an energy-saving oven for industrial large-scale production. It is mainly used for drying transformer cores and coils, drying spray-painted electrical cabinets and parts, drying rare earths, and drying casting sand molds. Heat treatment process for wide and thick plates drying, motor drying and other uses. The trolley-type material inlet and outlet method is adopted, which is suitable for automatic inlet and outlet of large quantities of workpieces. Effect of filler metal on vacuum brazing of cemented carbide and steel In the production process of Qianshi transformers, processes such as core preheating, coil pre-drying, coil dipping and drying, and resin curing are very critical and directly affect the quality of the transformer. Therefore, they have a negative impact on the temperature uniformity of the curing furnace and the reliability of the control system. The requirements are very high.
