Gas heating, hot water washing, boronizing and saponification integrated unit for steel wires

Abstract

The invention relates to a gas heating, hot water washing, boronizing and saponification integrated unit for steel wires. The unit comprises a hot water tank, a boronizing tank and a saponification tank which are sequentially arranged along the wiring direction of the steel wires. The steel wires are penetrated through from the front end of the hot water tank, sequentially pass the hot water tank, the boronizing tank and the saponification tank, and then are penetrated out from the back end of the saponification tank. The unit is characterized in that a flame path is arranged under the hot water tank, the boronizing tank and the saponification tank along length directions, bottoms of tanks and heat insulating materials are arranged around the flame path, one end arranged under the hot water tank of the flame path is closed, and the other end arranged under the saponification tank of the flame path is provided with a burner through burner blocks. The unit is skillful and reasonable in structure, the flame path is arranged under the hot water tank, the boronizing tank and the saponification tank, the burner is adopted to directly align to and heat the flame path, water, boronizing liquid and saponification liquid are heated through high temperature flames, and the unit is energy-saving, environment-friendly and field saving.

Description

technical field [0001] The invention belongs to the technical field of steel wire heat treatment-surface treatment equipment, and in particular relates to a steel wire gas heating hot water washing, boronizing and saponifying integrated unit. Background technique [0002] In the prior art, in order to improve the comprehensive performance of the steel wire, heat treatment and surface treatment are generally required for the steel wire. Generally speaking, the steel wire has to go through heat treatment, pickling, phosphating, hot water washing, boronization, saponification, drying and other processes during production, and each link has a great influence on the drawing performance of the steel wire. [0003] In the process of hot water washing, boronization and saponification of steel wire production, the hot water in the hot water tank, the boronization solution in the boronization tank and the saponification solution in the saponification tank all need to be heated to a su...

Problems solved by technology

At present, most domestic and international similar products are electric heating or steam heating, and their disadvantages are as follows: (1) Using electric heating, the energy consumption is particularly high, the heat utilization rate is low, and the climate temperature is different in winter and summer, The heating temperature required for the hot water tank, boronization tank and saponification tank is different, so the electric heating device may be in an abnormal working state in summer, resulting in a reduction in the service life of the heating device

(2) Using the steam heating method, the heat to maintain the temperature of hot water, boronized liquid and saponified liquid mainly comes from the heat release when the high-temperature steam changes from gaseous state to liquid state, so the demand for steam is huge and the cost is high. Moreover, the hot water after high-temperature steam reforming is discharged, which also causes a waste of energy.

In addition, the steam heating method needs to be equipped with a boiler to provide a site and related facilities for transporting steam, which occupies a large space and causes waste of raw materials and labor.
