Description
Przedmiotem wynalazku jest staliwo niskostopowe konstrukcyjne, przeznaczone na odlewy części pracuj ące w bardzo trudnych warunkach, j ak koła zębate, płozy w kombajnach węgłowych, profile do rynien zgrzebłowych, belki i ruszta do aglomerowni.The subject of the invention is low-alloy construction cast steel, intended for castings of parts operating in very difficult conditions, such as gear wheels, skids in coal shearers, profiles for scraper gutters, beams and grates for agglomeration plants.
Znane staliwo według polskiego patentu nr 151 898 zawiera wagowo: węgla 0,3-0,40%, krzemu 0,20-0,50%, maksimum 0,30% chromu, maksimum po 0,03 5% fosforu i siarki, manganu 1,10-1,40% i niklu 1,10-1,40%. Staliwo wykazuje wysokąwytrzymałość na rozrywanie, wysoką plastyczność i udarność oraz posiada dobrą lejność i dobrą spawalność.Known cast steel according to Polish patent No. 151 898 contains by weight: carbon 0.3-0.40%, silicon 0.20-0.50%, maximum 0.30% chromium, maximum 0.03 5% phosphorus and sulfur, manganese 1.10-1.40% and nickel 1.10-1.40%. Cast steel exhibits high tear strength, high plasticity and impact strength, and has good castability and good weldability.
Celem wynalazku jest uzyskanie staliwa o bardzo dużej wytrzymałości na rozrywanie i udarności, a o małej wrażliwości na zmianę grubości ścianki odlewu.The aim of the invention is to obtain cast steel with very high tear strength and impact toughness, and with low sensitivity to changes in the casting wall thickness.
Staliwo zawierające wagowo: węgla 0,30-0,40%, krzemu 0,20-0,50%, fosforu i siarki maksimum 0,03%, manganu 1,10-1,50%, według wynalazku zawiera wagowo: niklu 1,00-1,30%, molibdenu 0,20-0,30% i wanadu 0,05-0,12%.Cast steel containing by weight: carbon 0.30-0.40%, silicon 0.20-0.50%, phosphorus and sulfur maximum 0.03%, manganese 1.10-1.50%, according to the invention, it contains by weight: nickel 1 .00-1.30%, molybdenum 0.20-0.30% and vanadium 0.05-0.12%.
Drogą obróbki cieplnej można łatwo regulować: twardość, własności plastyczne i wytrzymałość staliwa. Przykładowo staliwo zawierające wagowo: węgla 0,33%, manganu 1,39%, krzemu 0,43%, fosforu 0,018%, siarki 0,014%, chromu 0,11%, niklu 1,11%, molibdenu 0,21% i wanadu 0,07%, po ulepszeniu cieplnym uzyskuje się następujące parametry:The following can be easily adjusted by heat treatment: hardness, plastic properties and strength of cast steel. For example, cast steel containing by weight: carbon 0.33%, manganese 1.39%, silicon 0.43%, phosphorus 0.018%, sulfur 0.014%, chromium 0.11%, nickel 1.11%, molybdenum 0.21% and vanadium 0.07%, after thermal improvement, the following parameters are obtained:
- wytrzymałość plastyczną R - 1089 MPa- plastic strength R - 1089 MPa
- wytrzymałość na rozrywanie Rm -1152 MPa- tear strength R m -1152 MPa
- wydłużenie A5 -10,5%- elongation A 5 -10.5%
- przewężenie Z - 30,2%- contraction Z - 30.2%
- udarność KCU - 4^^9 KJ/m2 - impact strength KCU - 4 ^^ 9 KJ / m 2
- twardość HB - 326- hardness HB - 326
- temperatura odpuszczania - 500°C.- tempering temperature - 500 ° C.
