PRODUCT CATEGORIES

Weier Furnace began as a service company and our commitment to service remains an integral part of our culture.
It has served to make us the premiere supplier of industrial furnace replacement parts and components, service and repair and service consulting service.
“The turn around time was above and beyond anything I had expected.” “It’s reassuring there are companies today who meet and exceed their customers’ expectations while producing a quality product”.
The product, the service, the communication and consistent professionalism at every level of the company is my gold standard for project realization.

Box resistance furnace stove structure and properties
    Box resistance furnace from the furnace and electrical control cabinet. Furnace and the furnace shell from the oven rack, lining, door, electric heating elements and door lifting mechanism and other components. Heating element arranged in multi-wall and bottom sides.
    Furnace temperature uniformity condition, mainly due to heating element layout, door seal and the state of insulation, usually before the furnace temperature is lower. Workpiece in high-temperature box furnace heating depends mainly on the surface of the furnace heating elements and thermal radiation. To improve the exchange of results of such furnaces, the production to take the following measures:
(1) to improve door sealing, heating, or heating elements inside the door, or openings in the furnace plus a shield to reduce radiation losses mouth.
(2) a reasonable arrangement of the workpiece, the more stringent requirements of the fire conditions, workpiece spacing of the workpiece diameter (or width) half, better heat transfer and productivity.
(3) furnace wall coated far-infrared coating to increase the radiation factor, but most paint can not long maintain its high radiation coefficient, affect the results.
(4) the use of corrugated furnace vault structure to improve the radiation heat transfer surface.
(5) improved heating element arrangement, the use of plate-like heating element, increasing the shelf components to reduce the radiation area and wire-line radiation shielding bricks. Set in a box furnace roof heating elements also improved heat exchange effect.
(6)using fire-resistant fiber lining to minimize heat build wall oven and heat dissipation.
