LCD Crawler Ceramic Heater
Various industrial equipment and large workpieces require local heat treatment before welding preheating and after welding stress relief to improve workpiece quality and enhance regional toughness. Currently, in large workpieces or field sites, equipment maintenance uses traditional, inefficient, high-energy-consumption high-frequency heating, flame heating, or costly super heating furnaces for heat treatment. Additionally, metal container drying and high-temperature heating employ outdated methods, such as: ① Steam pipe heating and water-oil jacket indirect conduction heating (which cannot meet certain high-temperature requirements, and containers are heavy, labor-intensive, and difficult to maintain). ② Destructive container heating using electric heating rod insertion (some materials cannot contact the heating element, or damaged rods contaminate materials, requiring material removal for repair). ③ External heating using electric furnace wire strung through ordinary porcelain tubes (line contact with container, small contact area, low thermal efficiency, and fragile porcelain poses safety risks).
● The crawler heater replaces these outdated methods and is an ideal product for local heating, field heating, and external heating.
● Crawler heater structure and applications:
Made of high-temperature resistant multi-strand heating wire and high-strength, high-temperature resistant ceramic components woven together using special processes. It can be arbitrarily bent along its length and is widely used for on-site heat treatment of various industrial equipment and workpieces, drying and heating of metal containers and pipelines, and high-temperature external heating of molds and dies.
●Crawler Heater Features:
1. Flexible: When heating containers or pipelines, it can be bent into arcs or circles to wrap around the surface. For large workpieces, it can be wrapped locally or laid flat for large areas. It adapts to various geometric shapes.
2. High working temperature, fast heating, high thermal efficiency, no pollution, uniform heating*, and supports automatic control.
3. High mechanical strength, good hot insulation performance, large contact area with heated objects, and long service life.
4. Easy installation and maintenance, low operating cost. Even if internal heating elements are damaged, external ceramic components can be reused.
● Crawler Heater Technical Specifications:
1. Dielectric strength: 2000V/1 minute
2. Hot insulation resistance: >5MΩ
3. Maximum working temperature: 1050℃
● Installation and Usage Instructions:
1. Depending on the size of the equipment or workpiece, single or multiple components can be evenly arranged. Fixing methods during installation include tying with stainless steel wire or forming a tightening ring with stainless steel strip and fastening with screws.
2. For temperature requirements and energy saving, cover the heater with 6-8 cm insulation material and a temperature controller.
3. Do not overlap heaters during use to avoid overheating zones that affect lifespan. Avoid breaking ceramic components to prevent exposure of heating elements and ensure safety.
4. The workpiece being heated must be reliably grounded. Operating voltage must not exceed 1.05 times the rated voltage.
LCD type crawler ceramic heater uses high-strength, high thermal radiation lead oxide ceramic components as insulation material and nickel-chromium wire cable as heating element. The assembled heater can be rectangular or triangular. The nickel-chromium wire cable and lead wires are welded using new technology, and all welded joints are embedded inside ceramic components for reliable insulation. The ceramic heater, when paired with control equipment, forms a complete heat treatment system. They are connected using special connectors, and extension wires can be configured based on the distance between the workpiece and control equipment. Length and size can be flexibly customized. The crawler ceramic heater should be selected according to the workpiece geometry, wall thickness, and heat treatment process.
