Cleaning and maintenance is one of those necessary evils: It takes time away from the project, but skipping it can be even more time-consuming and costly. Shotcrete pumps are no exception. Consider these tips for cleaning and maintaining high- and low-pressure pumps used to spray refractory shotcrete linings.
HarbisonWalker International (HWI), a supplier of refractory products and services, completed the first phase of a $9 million expansion at its manufacturing operations in White Cloud, Mich. The project will significantly increase warehousing space and add advanced-manufacturing and hydraulic press technologies. HWI’s 110,000-square-foot White Cloud facility currently employs approximately 140 people and produces brick and monolithic refractories utilized by the steel industry.
HarbisonWalker International (HWI) is investing to increase capacity by 25% at key steel refractory facilities. Most of the investment will be at its facility in White Cloud, Mich., which manufactures refractory products primarily for steelmakers. According to the company, approximately half of its capital investment dollars will have a direct positive impact on its steel industry customers. The investment will include expansion to accommodate new warehouse and shipping space, which is being constructed with American-made steel. Additional manufacturing space will house new technologies that improve production efficiency and worker safety.
Because of equipment improvements and material innovations – such as no-cement, colloidal silica, which offers optimal alkali resistance and bonding properties – contractors are installing monolithic refractories in areas of cement kilns once reserved for brick refractory.
HarbisonWalker International (HWI) announced that its Thomasville, Ga., monolithic/precast facility became the first of HWI's North American locations to earn certification to the new ISO 9001:2015 standard. HWI's South Shore, Ky., plant quickly followed to become the first refractory brick manufacturing plant in North America to achieve the same status. Both plants achieved this quality system recognition based on the recommendation of SRI Quality System Registrar.
Upstate Refractory Services (URS) of Newark, N.Y., acquired the assets of Hanyan-Higgins Company Inc., a refractory sales and service business. URS specializes in engineered precast refractory shapes; stack-bonded ceramic-fiber panels used in furnace roofs, walls and doors; refractory relines and repairs; and distribution of refractory materials. Hanyan-Higgins has been a distributor of Plibrico refractory products for over 60 years, and URS will continue to offer Plibrico across upstate, central and western N.Y.
By understanding the common signs of refractory failure, engineers can carry out maintenance to both fix a problem and avoid it in the future. In this article, SK Energy and Morgan Advanced Materials highlight seven signs to look out for.
