ABSTRACT:
A plant for chromizing metal articles, comprising: a furnace mounted on a framework tiltably about its transverse axis. Set up lengthwise within the furnace and rotatably about its longitudinal axis is a retort with two chambers and an appliance adapted to preclude the arbitrary pouring over of granular chromium-containing material from one chamber into another.
One of the chambers is fitted with a tube for supplying gas therein and another one with a reagent-supply tube and with a tube for discharging reaction products or feeding gas.
Said appliance comprises a screw secured in a retort throat and a partition arranged in front of the screw on the side of the working chamber and fitted with holes sufficient for the grains of the chromium-containing material to pass through but insufficient for the passage of articles.
Chromizing apparatus includes a horizontal mounted retort which is rotatable about its longitudinal axis, pivotal about its transverse axis and has a working chamber and an auxiliary chamber. Communication between the chambers is through a perforated plate disposed in front of a screw member relatively fixed in a reduced section of the retort; whereby in one direction of pivot and a first direction of retort rotation, the auxiliary chamber may be charged with grannular material and in the in the reverse directions of pivot and rotation the granular charge may be transferred to the working chamber.
