Abstract
A teeming trough for pouring molten metal into a mold. Cooling water jackets are formed at both sides of a horizontal body for molten metal teeming. Valves for adjusting cooling water feeds are disposed in cooling water feed paths for supplying cooling water into respective water cooling jackets. A lateral bend of the body at the forward end thereof is detected by a suitable sensor. The valves are controlled on the basis of the result of the sensor detection so that the balance between cooling water feeds to the water cooling jackets may be varied whereby a bend of the body can be corrected.
Claims6
A teeming trough for pouring molten metal into a mold comprising a horizontally extending body for pouring molten metal, water cooling jackets formed at both sides of the body, cooling-water feed paths for supplying cooling water into the water cooling jackets, means for adjusting cooling water feeds in the respective cooling-water feed paths, means for detecting a lateral bend of the body, and means for controlling the cooling-water feed adjusting means on the basis of a detection signal from the bend detecting means in such a manner that the cooling water feed to the water cooling jacket at the bent side of the body is decreased to lower the effect of cooling at the bent side.
A teeming trough for pouring molten metal into a mold comprising a horizontally extending body having a cross-sectional configuration of a top-open U shape for enabling molten metal teeming, a cover encompassing the outer side of the body, a water cooling jacket defined between the body and the cover in such a way as to permit cooling water to contact a substantially entire surface of the body extending along the cross section of the body, a rib projecting downwardly from the bottom of the body, and a clearance defined between the rib and the cover.
A teeming trough for pouring molten metal into a mold comprising a horizontally extending body for pouring molten metal, water cooling jackets formed at opposite sides of the body respectively, means for partitioning the interior space of each of the water cooling jackets into two compartments, upper and lower, cooling water feed paths for supplying cooling water into respective cooling compartments, means for adjusting cooling water feeds in the respective cooling water feed paths, means for detecting lateral and/or vertical bend of the body, and means for controlling the cooling water feed adjusting means on the basis of a detection signal from the bend detecting means in such a manner that the cooling water feed to the water cooling compartments at a bent side of the body is decreased to lower the effect of cooling at the bent side.
