Environment-friendly smelting furnace for nickel-based alloy powder coating

Abstract

The invention belongs to the technical field of smelting furnaces, and particularly relates to an environment-friendly smelting furnace for a nickel-based alloy powder coating. The furnace aims to solve the problem that an existing smelting furnace is not energy-saving and environment-friendly. According to the technical scheme, the furnace comprises a smelting furnace body, a smelting furnace cover body, a material storage tank and a purification heat absorption tank, wherein the smelting furnace cover body is arranged on the smelting furnace body, the material storage tank is arranged on thesmelting furnace cover body, a material conveying pipe is arranged on the material storage tank, a liquid storage cavity is formed in the material storage tank, a connecting pipe communicates the liquid storage cavity and the purification heat absorption tank, a water pump is arranged on the connection pipe, a liquid discharge pipe is arranged on the material storage tank and communicates with the liquid storage cavity, the purification heat absorption tank is arranged on the smelting furnace cover body, one end of an air inlet pipe extends into the smelting furnace body, the other end of theair inlet pipe extends into the purification heat absorption tank, and a gas exhaust pipe is arranged on the purification heat absorption tank. According to the furnace, the operation is convenient,the safety performance is good, the heat preservation effect is good, the energy consumption is reduced, waste gas in the smelting process can be purified, the heat in the waste gas can be absorbed and utilized, and the energy-saving and environment-friendly effects are realized.

Description

technical field [0001] The invention relates to the technical field of melting furnaces, in particular to an environment-friendly melting furnace for nickel-based alloy powder coating. Background technique [0002] Nickel-based alloy powder is a kind of alloy powder widely used in the market. The brand is divided into two types: high hardness and low hardness. This powder is the most widely used type of self-fluxing alloy powder, and has excellent comprehensive properties. Corrosion resistance, oxidation resistance, heat resistance, low stress abrasive wear resistance and good impact toughness; low melting point, wide solid-liquid phase temperature range, strong wetting ability to various substrates and WC particles, etc., and self-fluxing , Excellent wettability and spray welding, the spray welding layer has the characteristics of high hardness, corrosion resistance, wear resistance and heat resistance, and is difficult to cut; [0003] When melting nickel-based alloy powd...

AI Technical Summary

Problems solved by technology

[0003] When melting nickel-based alloy powder coatings, it is often necessary to use corresponding melting furnaces, but the existing melting furnaces for nickel-based alloy powder coatings are inconvenient to use, not energy-saving and environmentally friendly, and the waste gas generated during the melting process is directly discharged into the In the atmosphere, it not only pollutes the environment, but also wastes the heat in the exhaust gas, and the insulation performance and safety performance of the melting furnace need to be improved
