The two valve members of a sliding gate valve for pouring metal melts are made of abrasion-proof material and material which is relatively subject to abrasion, at least on its sliding surface, respectively. In use, wear grooves or recesses are formed in the sliding surface 9 of the valve member 12, which is subject to abrasion and these grooves are filled with a mixture 20 of abraded particles and metal particles or droplets which form a lasting seal between the sliding surfaces of the two valve members. <IMAGE> |
