摘要： The invention relates to the feeding of baking apparatus with green pellets, for instance of iron ore, supplied by pelletizing apparatus the output of which may fluctuate. The green pellets coming from the pelletizing apparatus, optionally after screening, is fed to a movable belt conveyor discharging to a fixed belt conveyor which in turn discharges to the baking apparatus. Measuring apparatus measures the mass flow rates of the green pellets discharging from both conveyors. The movable conveyor is moved parallel to the conveying direction of the fixed conveyor at a velocity proportional to the difference between the mass flow rates so that the depth of the layer of green pellets on the fixed conveyor is approximately constant.

摘要： A method for measuring the thickness of a body, characterized in that on each side of the body whose thickness is to be measured one point is selected, the points being situated on a common normal to the median plane of the material or substantially in proximity to such a normal, these two points being such that the planes tangential to the walls of the body at these points are substantially parallel. Optical rays are directed towards each of these points, and a high proportion of the rays emanating from these points are collected in the form of two distinct beams. These beams are subsequently oriented towards a common plane and the distance between the images resulting from the intersection of these beams with the plane is measured by a suitable means, this distance being indicative of the thickness being measured.

摘要： Iron ore is reduced in a blast furnace. Hot reducing gas is injected into the furnace at the level of the reserve zone; the gas can be reformed gas produced by partial combustion with oxygen of hydrocarbons preheated to about 650*C without pyrolysis. A reducing agent is injected into the furnace at approximately the level of the tuyeres; the agent can be coal-oil slurry, fuel oil, natural gas, or reformed gas.
