Sintered Stainless Steel Dust Guard (P/N 1800822) The General Monitors Sintered Stainless Steel Dust Guard protects the sensor from fine particulates and is designed for use in windy conditions. It should, however, be used only in dry environments because the sintered disc has a tendency to
The Steel & Mines Department is one of the important Departments of Government of Odisha. It works for the development of the mineral resources of the State under the regulatory powers. It also encourages and provides support for value addition and end-use of minerals in the State
Compass' prime requirements were for 316 stainless steel construction and inspection hatches for dust filtering and sampling needs. The units had to be fully enclosed with a flange fitting directly onto their existing loading spout. The end result was an integrated unit with hatches for the air to escape, but with all the dust contained.

Raw materials Steel production. Coke. Coking coal is converted to coke by driving off impurities to leave almost pure carbon. The coking coal is crushed and washed. It is then 'purified' or 'carbonised' in a series of coke ovens, known as batteries, where the coking coal is heated to 1000-1100ºC in the absence of oxygen for 12-36 hours.
