Ring heat treatment furnace equipment structure:

The ring heat treatment furnace is composed of a furnace body, a movable furnace cover and a control system.

1. The shell of the furnace body is welded into a frame structure by section steel and steel plate.

2, the furnace cover support adopts channel steel and guide rail combination mobile.

3, after our long-term production experience and user requirements, we also specially designed the chromium manganese nitrogen furnace mouth retainer, the purpose is to protect the cotton of the furnace mouth from being damaged by the workpiece, so that the heat is not lost, so as to ensure the uniformity of the furnace temperature. (This is specially designed for large ring pit furnaces)

4. The heating element is arranged on the furnace side with high resistance alloy oc25al5 resistance belt produced by Shanghai Electrotechnical Alloy Factory.

5, the furnace body is made of high purity aluminum silicate fiber cotton pressed into plates, the furnace wall hanging resistance belt heating, the main characteristics of the structure is energy saving, high heating effect, can quickly make the temperature rise. And not easily damaged. Furnace wall heating element is ocr25al5 resistance band.

6, the bottom part of the furnace due to load-bearing, the use of high aluminum refractory brick masonry, the core of the furnace using a large trap small ring approach, heating inside and outside, which increases the uniformity of the furnace temperature, but also reduces the power consumption of the furnace, while reducing the configuration of the furnace power, so that the use of transformer space is larger. Since there is no resistance wire at the bottom, we add chromium manganese nitrogen pad iron on the top to increase the circulating temperature of the ring.

7, the furnace cover adopts hydraulic lifting, motor control automatic walking. In order to save expensive plant and land investment, we specially designed a common lifting mechanism for multiple electric furnaces to avoid the waste situation of one furnace and one furnace cover.

8, control using a color liquid crystal paperless recorder record, the recorder replaces the conventional medium and long chart with paper recorder, due to the large well furnace temperature area, the previous basic use of medium and long chart with paper multi-point recorder, and the table is prone to disorderly dot phenomenon, often hit a line, but full of stars, so that customers are very dissatisfied with the process curve, while fax is not convenient, Because the paper is so wide. The advantages of color LCD paperless recorder are clear display, digital, curve, bar chart can be selected, the working date and time are clear at a glance, the deviation temperature can be adjusted, and the test can be printed or emailed to the user with the equipped u disk.

9, the use of multi-area independent control, the use of Shanghai Guolong table TTCW-32A, pid automatic power regulation, thyristor control.

Electrical part of ring heat treatment furnace:

1, pid control, Shanghai Guolong intelligent TTCW-32A power meter control, paperless record 1.

2, contactor and thyristor double protection control. Contactor and thyristor two-way control is also specially designed by us, this design makes up for the mutual control weakness, thyristor temperature control precision is high, but easy to breakdown and turn off, there is conduction and leakage phenomenon, easy to harm the staff and make the equipment overtemperature and destroyed; The contactor is better, and the electricity can be turned off by shutting it off, but the temperature control accuracy is not enough, and it is easy to make the furnace temperature buffer, so the joint control of the two is ideal and reasonable, and it is also my crystallization over the years.

3, ceramic thermocouple, k type.
