Refractory services manufacture, install and repair refractory shapes and monolithic refractories. Refractory shapes are hard, heat resistant materials that are suitable for applications which require high temperature strength, wear resistance, electrical or thermal insulation, or other specialized characteristics. Monolithic refractories are liners for furnaces, boilers, or other thermal processing equipment. To produce refractory shapes and monolithic liners, refractory services perform a variety of fabrication processes. Casting pours liquid into a mold and allows it to dry into a solid shape. Injection molding disperses ceramic powder in a plastic or wax binder, melts the material, and then injects the mixture into a die cavity. Sintering or firing is a thermal consolidation process that uses diffusion to bond ceramic particles together. Mechanical pressing places dry ceramic powder, usually with a wax binder or lubricant, in a die and punch set.
Refractory services are located across the United States and around the world. They meet various certification and quality requirements. ISO 9001 establishes requirements for organizations whose business processes range from design and development to production, installation, and servicing. ISO 9002 establishes requirements for organizations whose business processes include production, installation, and service, but do not include design and development. QS 9000 is a quality standard for suppliers of DaimlerChrysler Corporation, Ford Motor Company, and General Motors Corporation. QS 9000 is based on the 1994 edition of ISO 9001, but contains additional requirements that are particular to the automotive industry.
