Description

Vynález sa týká vložky z ocelového plechu pre výrobu dusaných pánví.The invention relates to a steel plate liner for the production of stew pans.

Pre vyhrievanie dusaných pánví, používaných pre odlievanie ferosilícia, používala sa doteraz vložka z ocelového plechu o hrúbke 12 mm. Táto ocelová vložka sa vplyvom silnej intenzity sálavého tepla zo zdroja naftového, horáka rýchlo deformovala, čo viedlo k poškodzovaniu výdusky pri vytahovaní vložky. Samotné vyhrievanie dusaných pánví bolo nerovnoměrné, čo málo za následok nízku kvalitu výdusky pánví. Vo váošine podnikov vyrábajúcich ferosilicium táto otázka nie je aktuálna, nakotko sa bežne pre odlievanie tohto výrobku používajú panvy murované šamotom, ktoré sú však značné drahšie.Up to now, a 12 mm steel sheet insert has been used to heat the stew pans used for casting ferro-silicon. This steel liner deformed rapidly due to the high intensity of radiant heat from the oil burner source, resulting in damage to the lining when the liner was removed. The heating of the stewed pans alone was uneven, which in turn resulted in poor quality of the pan lining. In the case of many ferro-silicon companies, this issue is not relevant, since fireclay pans are commonly used for casting this product, but these are considerably more expensive.

Spomínané nedostatky sú vyriešené vložkou z ocelového plechu pre dusanie pánví, ktorá sa podlá vynálezu vyznačuje tým, že na vnútornej straně má namurovanú vrstvu šamotovej tehly o hrúbke od 33 do 38 mm.Said drawbacks are solved by a steel sheet liner for pan ramming, which according to the invention is characterized by having a coated chamotte brick having a thickness of 33 to 38 mm on the inside.

Ochrannou tenkou vrstvou zo šamotu na ocelověj vložke podlá vynálezu sa zabráni miestnemu nadměrnému prehrievaniu oce-A protective layer of chamotte on a steel liner according to the invention prevents local overheating of the steel.

Claims

Steel liner for heating stew pans, characterized in that the inner liner liners and their deformation. The radiant heat coming from the source of the oil burner passes through a layer of fireclay material in which it accumulates and, by passing through the sheet, uniformly heats the entire lining of the ladle, which sheet protects the sheet itself from damage. At the same time, a layer of fireclay material ensures a uniform temperature distribution over the whole lining of the ladle, thereby achieving a higher strength.

The steel insert is produced by twisting a 12 mm thick sheet with the following welding. On the bottom part inwards, weld a steel annulus with a thickness of 3 mm and a width of 40 mm for the basic attachment of the first row of fireclay bricks. The fireclay brickwork is carried out upright along the height of the steel liner using the fireclay mortar, ie. fireclay flour and water as binders.

The steel liner according to the invention can be used wherever steamed pans and crucibles are used, which need to be heated after steaming.

YNÁLEZU side has a coated layer of fireclay brick with a thickness of 33 to 38 mm.
