Abstract

DC60 (03/12/40) A method for welding short pieces of steel exiting the furnace heated in the rolling line, where the line consists of segments (10) between the heating furnace (11). And rolling platform at one, pulling unit (14), at least a roller track for transporting short steel rods, a sliding welding assembly (20) with a welding rod (31) and an emergency cutting knife ( 13) where the rear end of the rolled short steel rod (12a) is welded to the leading end of the short iron rod (12b) that was subsequently taken from the furnace (11) while the short steel rod ( 12) is being moved by welding assembly (20) worn on a sliding wheelbarrow (19) in which a movable wheelbarrow (19) is conditional. Stationary While it will wait Touch position Between the ends of the short steel rod (12) that will be coupled, there is a second condition as it progresses where it will speed in Actually rolling, short iron rods (12) are taken with the flanges (31) of the welding unit (20) and welded the ends of the short rods (12) and the conditions that Third, which is a retreat After the sliding wheelbarrow (19) returns to its original position, the connection process is connected from the soot removal process performed by the soot removal unit (16) on the front surface. Of the short rod (12) and at least those areas of the short rod (12) that work together with the claw (31) are removed and by the process of scraping in the parallel plane of Leading and trailing ends Of short steel rods (12) operated by a scraper unit (29) mounted with a minimum of one rotating blade (27) and mounted on a sliding wheelbarrow (19) which It leads to the immediate source of the welding assembly (20), where the welding procedure is followed by a flash removal procedure performed by the flashover unit (38) while the shortened rod (12). The extrusion line is moving. For short steel rods, which use the method Sliding welds at the outlet of the heating furnace, as in the claim. Whichever one before The line consists of a section (10) between the heating furnace (11) and the rolling platform at one, the pulling unit (14), at the most one roller track to transport. Send short, tired steel rods, assembled for Movable welding (20) including welding claws (31) and emergency cutting knives (13), where the line consists of end leads of the pulling unit (14), stationary soot removal unit. One (16), a sliding wheelbarrow (19) with interchangeable sliding on its relative slope (23), which a sliding wheelbarrow (19) will sustain at least that. Ultimate welding assembly (20) with flanges (31) for clamping shortened steel rods (12), scraping unit (29) and sliding soot removal unit (30) with a sliding wheelbarrow. (19) There will be the first part (19a) as it waits for a short piece of steel (12) leading to its destination in Instantly of the stain removal unit 1st stationary soot (16) and second end of motion (19b), transport path (37) with rollers (25) worn on support that rotates around the pivot (24). Which has the first working position and Second draw position, temperature stabilization system (34), emergency cutting knife (13) method for welding short steel rod released from the heat treatment furnace in the rolling mill. The line consists of segments (10) between the heating furnace (11) and the rolling platform at one, the pulling unit (14), at a minimum, the roller track to transport the short steel rods, the sliding welding assembly. Yes (20) with a welding rod (31) and a cleaver knife (13) where the rear end of the rolled short steel (12a) is welded. With the leading end of the short steel rod (12b) taken thereafter from the furnace (11) while the short steel rod (12) is being moved by the welding assembly (20) worn on the sliding wheelbarrow. Yes (19), in which a movable wheelbarrow (19) has a stationary condition. While it will wait Touch position Between the ends of the short steel rod (12) to be splice there is a second condition as it progresses where it will have true iron speed, holding the short rod (12) with the canine (31). ) Of the welding unit (20) and welding the ends of the short rod (12) and the conditions that Third, which is a reverse where the movable wheelbarrow (19) returns to its original position, the connection procedure is connected from The soot removal process was performed by the soot removal unit (16), the front surface of the short steel bar (12) and at least those areas of the section. The shortened steel (12), working in conjunction with the claw (31), is removed and by a slanting process in the corresponding plane of the The leading and trailing ends of the short rods (12) operated by the screed unit (29), mounted by Minimal rubber, one rotating blade (27) and worn on a sliding wheelbarrow (19) leading to the immediate origin of the welding assembly (20), where the welding procedure is followed by a procedure. The flashover was performed by the flash suppression unit (38) while the short dead iron rod (12) was moving. For short steel rods Which uses method principles Slidable weld at the outlet of the heating furnace, as in any of the previous claims. Where the line consists of a section (10) between the heating furnace (11) and the rolling platform at one, the pulling unit (14), at the most one roller track to transport the short iron rods, assembly for Movable welding (20), including welding claws (31) and emergency cutting knives (13). To the destination of the pull unit (14), the first stationary soot removal unit (16), the sliding wheelbarrow (19) with the alternating slide on its relative slope ( 23) which a sliding wheelbarrow (19) will sustain at least that Ultimate welding assembly (20) with flanges (31) for clamping shortened steel rods (12), scraping unit (29) and sliding soot removal unit (30) with a sliding wheelbarrow. (19) There will be the first part (19a) as it waits for a short piece of steel (12) leading to its destination in As soon as the stationary soot removal unit (16) and the second end of travel position (19b), the transport path (37) with the rollers (25) worn on the support at Turn around the pivot (24), which has one working position and Second stroke position, thermostats (34), emergency cutters (13)
