Problems solved by technology

[0004] At present, in the prior art, there have been gas-fired galvanizing furnaces that use thermocouple sensors to measure the temperature in the furnace in real time and accurately. However, the temperature in the furnace can only be detected and cannot be automatically adjusted. When the temperature in the furnace is too high At this time, it is necessary to manually cut off the heat source, and then observe the temperature change, which is time-consuming and laborious, and the safety factor is not ideal.

Abstract

The invention relates to a controllable-temperature gas galvanizing furnace. The controllable-temperature gas galvanizing furnace comprises a furnace body, a heating element, an inner cylinder, a furnace frame, a base, a thermocouple sensor and a controller, the thermocouple sensor consists of a conjunction box, a connecting device, a protective tubes and a sensor, the conjunction box is connectedto the controller, and the controller can control a telescopic member at a lower part to push or retract a cooling plate according to the temperature information fed back by the thermocouple sensor;the temperature in the furnace can be monitored and fed back in real time through the thermocouple sensor, and the temperature in the furnace can be automatically adjusted to achieve temperature control, and the safety factor is high.

Description

technical field [0001] The invention belongs to the field of gas galvanizing furnaces, and in particular relates to a gas galvanizing furnace with controllable temperature. Background technique [0002] Powder galvanizing has the same anti-corrosion performance as hot-dip galvanizing, and the cost is much lower than hot-dip galvanizing, and the consumption of zinc is also lower. The surface brightness of powder galvanized finished products is better, and the tensile load of fasteners is higher than that of hot-dip galvanized parts. The development of electric power, transportation, railway, construction, chemical industry and other industrial technologies has put forward higher requirements for the corrosion resistance of fasteners (bolts, nuts, etc.), which must be long-lasting and low-cost. Therefore, hot-dip galvanizing has been widely used. However, the screwing performance of the workpiece after hot-dip galvanizing is poor, which affects the construction and assembly....
