Objectif The main point of the investigation is to qualify and quantify the emissions at cold-bonded refractory heat-up. The impact of this emission on ambient air quality at different work places in the concerned shop is then examined.For the needs of the steel and iron industry, refractory brick manufacturers produce materials which are cold-bonded by organic compounds. Through this bonding, the refractories obtain good cold mechanical strength and their handling and installation for linings (reaction vessels, casting and transport of liquid metal, etc) are greatly facilitated. The most widely used of organic bonding materials permit development of a carbon bond after pyrolysis which ensures good material thermo-mechanical properties and an excellent corrosion resistance with regard to liquid slags and metals.The organic bonding materials can be partially eliminated during the actual refractories manufacturing process (tempering). But very often, the heat-up of metallurgical reaction vessels is accompanied by a high residual emission which can pose serious health problems in the industrial bays.The objective of this research is to supply the means necessary so that the iron and steel profession can correctly administer to this particular aspect of siderurgical nuisance, both in economic terms and in terms of protection for exposed workers:(i) In collaboration with cold-bonded refractory suppliers, to orient the manufacture and application of these refractories in such a way that the residual emissions of these materials at heat-up in iron and steel shops can be minimized.(ii) Using research measurement data, to define an effective prevention program: individual and collective protection of exposed workers adapted to the level and complex quality of cold-bonded refractory emission; modalities of cleaning up the bays if this is necessary.(iii) To elaborate adapted and permanent experimental means to be able to follow and evaluate the emissions of newly marketed materials resulting from the evolution of techniques in the refractory industry and in the siderurgical processes in the shops treating the liquid metal.
