Ingot mold

The cells are fed semicontinuously and produce both magnesium and chlorine (see Alkali and chlorine products). The magnesium collects in a chamber at the front of the cell, and is periodically pumped into a cmcible car. The cmcible is conveyed to the cast house, where the molten metal is transferred to holding furnaces from which it is cast into ingots, or sent to alloying pots and then cast. The ingot molds are on continuous conveyors. 

Vacuum and Atmosphere Melting. A coreless high frequency induction furnace is enclosed in a container or tank which can be either evacuated or filled with a gaseous atmosphere of any desired composition or pressure. Provision is made for additions to the melt, and tilting the furnace to pour its contents into an ingot mold also enclosed in the tank or container without disturbing the vacuum or atmosphere in the tank (Fig. 2).

Carbothermal reaction requires temperatures in excess of 2000°C. After ca. 1 to 2 h the continuously operating furnace is tapped with an auxiliary electrode. The liquid silicon (m.p. 1413°C) is collected in pans or ingot molds. If necessary, further metallurgical processes such as slag extraction or air blasting with reactive gases can be carried out to rid the silicon melt of included metallic and non-metallic impurities, before the silicon solidifies into brittle blocks. 

Latest developments concern the quenching of liquid silicon by feeding a jet of molten silicon into water (water granulation) or casting into cooled ingot molds. The material thus produced exhibits an improved reactivity in the synthesis of methylchlorosilanes (Rochow process). 

With the ultrasonic treatment of a melt in the ingot mold, the narrowing of the supercooling region near the solidification front with development of cavitation processes occurs due to an inner heat source without preliminary overheating of the melt in a holding furnace. Besides that, the melt in the liquid bath is continuously supplied by additional solidification nuclei as it passes through the zone of the cavitation treatment. 

For melting up h> 2 oz. of gold or silver rapidly, witliont the use of a furnace. In this arrangement the two parts of the ingot mold slide on each otlier, to enable ingots of any width to be cast, aod the blowpipe is part of the rocking stand. 

When the metal is melted in the shallow crucible of molded carbon, till the whole apparatus over so as to fill the ingot mold. 

Molten metal poured above its melting point is chilled at the walls and bottom of the ingot mold and begins to solidify. The molten metal in the center cools more slowly and contracts as it cools. As the metal solidifies at the exterior of the molten zone and contraction continues a depression or in its worst condition a pipe develops in the center of the ingot. 

CAS 68439-86-1 EINECS/ELINCS 215-145-7 Uses For casting of refined copper, copper alloy, and aluminum as protective coating on ladles, troughs, etc. made from fused silica ceramic fiber, calcium silicate, castable all metal equip, and tools exposed to molten metal (ladles, sow molds, ingot molds, metal troughs) floor areas around mold stations, furnaces, ladles Features High heat transfer resist. 

Ingot molds made from treated cast irons have 50-70% higher strength than regular cast irons with lamellar graphite (Dubinin and Abakumov 1972).
