This factory (run by the LuaViet Metallurgic Materials JSC) made refractory bricks which are used to line electric arc furnaces for steel production (to stop the furnace itself from melting). The finely ground raw mineral (a relatively pure form of Magnesium Oxide) was mixed with a polymer binder, compacted into a precisely shaped brick using the huge mechanical press shown here and then fired (at a relatively low temperature of around 200 centigrade) to form the finished product, which was then palletised and shrink-wrapped ready for delivery to the client. This factory makes a few tens of tonnes of bricks per week.
