Problems solved by technology

Because there is no steel industry in China that specializes in the production of steel suitable for making steel toe heads, it has always been replaced by ordinary steel plates. Replaced by some low-alloy steel, because these low-alloy steel is not professionally designed for this industry, so the product quality is unstable
However, the chemical composition of the products produced by domestic iron and steel enterprises is not very stable. For example, the carbon content may vary by 0.05-0.1% for the same brand of steel from the same manufacturer, which brings great trouble to heat treatment.
Some experienced steel toe manufacturers use repeated heat treatment tests and inspections to find a suitable heat treatment process in order to meet the requirements, which often delays production and fails to deliver on schedule; especially some steel toe manufacturers do not have professional testing In the case of equipment and technical personnel, waste and compensation caused by unqualified products often occur

Embodiment Construction

[0014] refer to figure 1 , The heating chamber 1, the quenching chamber 2 and the tempering chamber 3 of the present invention are separated by a heat insulating plate 8 and a heat insulating plate 2 12. The heating chamber inlet door 7 and the tempering chamber outlet door 14 are located at the two ends of the heat treatment industrial furnace, and the heat shield one 8 and the heat shield two 12 have a quenching chamber inlet door 10 and a tempering chamber inlet door 13 respectively. These four doors can be closed automatically after the steel toe head pendant passes through the four import and export doors.

[0015] Heating resistance wire one 19 and thermocouple temperature sensor one 18 are arranged in the heating chamber 1 . There are heating resistance wire two 16 and thermocouple temperature sensor two 15 in the tempering chamber 3 . Quenching cooling cylinder 17 is arranged in the quenching chamber 2, and the steel toe head pendant 4 after the liquid requirement in...

Abstract

The invention relates to an intelligent heat treatment industrial furnace of a safety shoe antisquashy steel wrapping head, which is provided with a heating chamber, a quenching chamber and a tempering chamber, wherein heating resistance threads are arranged in the heating chamber and the tempering chamber, and a quenching cooling cylinder is arranged in the quenching chamber. Tracks are arrangedin the heating chamber, the quenching chamber and the tempering chamber, are provided with track ascending and descending hooks, and are driven by a motor. A pumping channel is arranged between the heating chamber and the tempering chamber. An output interface of an industrial personal computer is respectively connected with a thermocouple temperature sensor, the heating resistance thread, the track ascending and descending hook, a pendant track and an exhaust fan via digital-analog conversion A / D. The technology for heat treatment of different steel is pre-stored in the industrial personal computer, the heat treatment control parameters can be set automatically, and the output interface of the industrial personal computer is respectively connected with parts needing control via digital-analog conversion, so the heat treatment process can be precise, and the quality of the wrapping head is ensured. The pumping channel between the heating chamber and the tempering chamber can guide hotair in the heating chamber into the tempering chamber for preheating, reduces energy consumption and increases the production efficiency.

Description

technical field [0001] The invention relates to an intelligent heat treatment industrial furnace for anti-smashing steel toe caps of safety shoes. Background technique [0002] Due to the continuous improvement of people's safety awareness in recent years, the demand for labor safety shoes is also rising, and the requirements for their safety performance are also getting higher and higher. The global demand for anti-smashing safety shoes has reached 90 million pairs, especially more and more products are exported to the EU. While a large number of exports have brought huge profits to the safety shoes industry, it has also brought huge benefits to the industry. challenge. Because there is no steel industry in China that specializes in the production of steel suitable for making steel toe heads, it has always been replaced by ordinary steel plates. Some low-alloy steels are used instead, because these low-alloy steels are not professionally designed for this industry, so the...
