Application background:
Industrial furnaces, also known as industrial furnaces, are equipment made of refractory materials for calcining materials or products. As the country's requirements for environmental protection increase, most of the current industrial kilns use natural gas as the main fuel to achieve the calcination process. The demand is mainly applied in industries such as cement rotary kilns, glass tank kilns, steel wire box kilns, ceramic shuttle kilns and Other inorganic materials. In the calcination process, it is necessary to precisely control the amount of gas and air intake to achieve the control of the calcination process and production quality. This article demonstrates related applications of customer pain points of steel box kilns.
1. On-site requirements
Industrial kilns for steel wires and steel ropes need to regulate the mixing ratio of air and gas to reduce steel wire oxidation and control decarburization. The high-speed convection burners are closely arranged sideways, and the temperature in the furnace is reasonably organized to ensure the uniform and stable heating quality of the heat-treated steel wire. Customers have strict requirements on the accuracy and stability of sensors and the convenience of routine calibration of products.

Response curve required by customers
3. Current customer pain points and problems
1. Whether the emission standards of industrial kilns meet the VOC environmental assessment standards;
2. The accuracy of imported products currently used by customers is unstable; the drift of differential pressure in a small range is large;
3. It is inconvenient to stop production inspection of an imported product currently in use by a customer. Due to the mid-air operation and high temperature, it is necessary to open the back cover to connect to the HART line during the product reset to zero once a month, which is extremely inconvenient and leads to working hours. Delay
4. Sudden maintenance by customers, long production cycle of imported products, delay in construction period, urgent need for localized and convenient services.
Selected products:
1. JYB-810DC (±500pa)
2. JWB-241N (0-1000℃)
3. JQB-G-VOC (VOC, VOCS, etc.)
Product advantages
1. JYB-810DC adopts the principle of single crystal silicon, the accuracy can reach 0.075%.FS; the drift in normal use is extremely low, and the linearity is good.
2. While the JYB-810DC adopts the back-end HART debugging mode, it has a built-in instrument panel with one-key zero reset setting, which is extremely convenient for customers to conduct monthly inspections.
3. JYB-810DC adopts easy-opening front cover design, which is very convenient; and the rear wiring diagram is added.
4. JQB-G-VOC can send data directly to the environmental protection platform to meet customers' concerns about emissions EIA.
5. JWB-241N adopts high temperature thermocouple to meet customer's requirements for temperature feedback.
