Description
본 발명은 스테인레스톱의 제조 방법에 관한 것으로 특히, 내마모성과 윤활성 및 내부식성이 양호하도록 한 것이다.The present invention relates to a method for producing a stainless saw, in particular, to provide good wear resistance, lubricity and corrosion resistance.
종래의 톱의 재질은 철재 또는 스테인레스로 제작되고 있다. 철재의 경우는 장시간 사용하지 않고 방치하거나, 습기가 차면 톱의 표면이 부식되어 톱날의 훼손은 물론 윤활성이 떨어져 톱질이 잘 되지 않으며, 보관이나 사용도중 충격을 받으면 톱이 휘어져 사용이 불가능하게 되는 문제점이 있었다.The material of the conventional saw is made of steel or stainless steel. In the case of steel, if left unused for a long time or the moisture gets wet, the surface of the saw is corroded and the saw blade is damaged and lubricity is poor. There was this.
또 철을 주성분으로 한 톱은 경도가 낮아서 톱의 사용으로 톱날이 무디어지는 정도가 심하므로 목수일을 하는 사람의 경우는 다수개의 톱을 가지고 다니면서 수시로 톱날을 그라인딩(grinding)하여 사용하여야 하는 문제점이 있고, 일반적인 스테인레스톱(저니켈, 저크롬주강)은 인장 강도, 연성, 내충격성, 피로 한도등의 특성은 좋으나 내마모성과 내식성 및 윤활성이 약하여 톱으로서의 기능이 미흡하였다.In addition, the saws mainly composed of iron have low hardness, so that the saw blade is blunted by the use of saws. Therefore, a carpenter has to carry a number of saws and grind the saw blades from time to time. In addition, general stainless saws (low nickel, low chrome cast steel) have good characteristics such as tensile strength, ductility, impact resistance, fatigue limit, etc., but they have poor abrasion resistance, corrosion resistance, and lubricity.
본 발명은 이러한 문제점을 해결하고자 스테인레스톱을 제조하여 스테인레스를 열처리, 전해 연마 등의 처리공정을 거쳐 내마모성과 내식성 및 윤활성이 우수한 톱을 제조함을 목적으로 한다.An object of the present invention is to produce a saw having excellent wear resistance, corrosion resistance and lubricity through a process such as heat treatment, electropolishing, stainless stainless to solve this problem.
상기와 같은 목적은 스테인레스 강판을 1100~1200℃의 온도로 가열하여 수소가스를 이용하여칭(quenching)하는 열처리 공정과; 상기 열처리된 스테인레스 강판을 롤러를 이용하여 표면을 평활하게 하는 롤처리공정과; 상기 롤처리공정을 마친 스테인레스 강판을 템퍼링(empering)하는 공정과; 상기 템퍼링 공정을 마친 후 표면을 연마한 스테인레스강판을 전해액에 침지시켜 전해 처리하는 전해연마공정과 톱날을 성형하는 공정결합으로 구성되어 달성된다.The purpose is to heat the stainless steel sheet to a temperature of 1100 ~ 1200 ℃ using hydrogen gas A heat treatment step of quenching; A roll treatment step of smoothing the surface of the heat treated stainless steel sheet using a roller; Tempering the stainless steel sheet after the roll processing step; After completion of the tempering process is achieved by electrolytic polishing process of immersing the surface of the stainless steel plate immersed in the electrolytic solution electrolytic polishing process and forming a saw blade.
이를 공정별로 상세히 설명하면 다음과 같다.This will be described in detail by process.
열처리 공정은 스테인레스 강판을 가열로를 이용하여 온도를 1100~1200℃로 가열한 후에 수소가스를 이용하여 스테인레스 강판의 온도가 300~400℃되게칭한다.In the heat treatment process, the stainless steel sheet is heated to a temperature of 1100 to 1200 ° C. using a heating furnace, and then the temperature of the stainless steel sheet is 300 to 400 ° C. using hydrogen gas. It is called.
1100~1200℃의 온도 가열로 오스트나이트(austenite)의 스테인레스 강판이칭으로 마르텐사이트(martrensite)로 되면 부러지거나 깨지기 쉬우므로 Ms 이상의 온도인 300~400℃까지만 냉각한다.Austenitic stainless steel sheet was heated by heating at 1100 ~ 1200 ℃. When martensite is broken, it is easy to be broken or broken, so it cools only to 300 ~ 400 ℃, which is Ms or more.
롤처리 공정은 상기 열처리 공정을 한 후 스테인레스 강판을 롤러를 이용 냉간 가공하여 표면을 평활하게 하면서 두께를 일정하게 하기 위하여 롤을 이용하여 작업을 하는 공정이다.The roll treatment process is a process in which a stainless steel sheet is cold-processed using a roller after the heat treatment process, and works using a roll to make the surface smooth while smoothing the surface.
열처리 공정을 마친 후 24시간 이상의 시간이 경과되면 상온취성이 나타나 스테인레스 강판이 취약하게 되므로 24시간 이내에 롤러작업을 하여야 한다.After 24 hours or more after finishing the heat treatment process, the room temperature brittleness will appear and the stainless steel sheet will be vulnerable, so the roller work should be done within 24 hours.
스테인레스 강판을 인입하는 쪽의 롤은 상하게 위치하여 스테인레스 강판을 인입하고 중간의 롤은 다수개를 이용하여 굴곡을 주게 위치하여 롤 사이를 파행 진행하면서 열처리 공정에서 변형된 스테인레스 강판이 평면으로 되면서 두께가 일정하게 된다.The roll on the side of the stainless steel sheet is placed upright so that the stainless steel sheet is drawn in, and the middle roll is placed to bend by using a plurality of intermediate rolls. It becomes constant.
템퍼링공정은 상기와 같이 처리한 스테인레스판을 280~320℃로 가열하여 저온 템퍼링(empering)처리한다. 열처리와 냉간 가공에 의하여 생겼던 내열취성과 내부응력이 탬퍼링의 실시로 스테인레스강의 내열취성을 제거하고, 동시에 냉간 가공에 의한 내부응력이 제거되며, 정방형의 마르텐사이트는 산소를 석출하여 입방형에 가까운 고용체와 초미립자로 석출된 카아바이드(carbide)와의 불균일 혼합물로 변화하여 경도는 감소하나 인성은 증가한다.In the tempering process, the stainless steel plate treated as above is heated to 280-320 ° C. to be subjected to low temperature tempering. The heat embrittlement and internal stress created by heat treatment and cold working remove the stainless steel's heat embrittlement by tampering, and at the same time, the internal stress by cold working is removed, and the square martensite precipitates oxygen and is close to cubic. It is converted into a heterogeneous mixture of solid carbide and carbide precipitated as ultra-fine particles, reducing hardness but increasing toughness.
연마공정은 상기 템퍼링된 스테인레스 강판을 버프(buff)연마한다.The polishing process buffs the tempered stainless steel sheet.
전해연마공정은 인산, 황산, 초산, 무수크롬산, 제라지렌으로 조성된 전해액에 상기 공정을 실시한 스테인레스 강판을 25~30초 동안 침지시켜 전해연마한다.In the electropolishing process, the electrolytic polishing is performed by immersing the stainless steel plate subjected to the process for 25-30 seconds in an electrolyte solution composed of phosphoric acid, sulfuric acid, acetic acid, chromic anhydride, and gerazylene.
이때에 스테인레스 강판 표면의 철분은 용해되면서 이온화된 크롬이온에 의해 스테인레스 강판의 표면에 크롬막이 형성된다. 이 크롬표막은 광택과 윤활성이 있으면서 내구성이 매우 강하게 된다.At this time, the chromium film is formed on the surface of the stainless steel sheet by the ionized chromium ion while iron is dissolved on the surface of the stainless steel sheet. This chrome surface is glossy and lubricious and extremely durable.
톱날형성공정은 사용하고자 하는 목적에 맞는 톱날을 형성하는 공정이다.A saw blade forming process is a process of forming a saw blade suitable for the purpose to be used.
이상과 같은 공정을 거친 스테인레스 강판은 열처리에 의하여 경도가 강화되었고 톱의 사용으로 톱날이 무디어지지 않아서 톱날을 자주 그라인딩하여 날을 세워 주는 작업 시간과 경비가 절감되며, 또 저온 템퍼링처리에 의하여 인성이 증가됨과 동시에 전해 처리하여 스테인레스 강판의 표면이 평활하게 형성된 크롬막에 의해 표면이 견고하고 미려할 뿐 아니라 미끄러워 톱질이 원활하고, 습기가 있는 곳에 장기간 방치하여도 녹이 슬지않아 사용 수명이 길어지는 효과가 있다.The stainless steel sheet undergoing the above process is hardened by heat treatment and the saw blade is not blunted by the use of the saw, so the saw blade is often ground and the work time and cost for building the blade are reduced, and the low temperature tempering treatment Increased and electrolytically treated, the surface of stainless steel plate is smooth, and the surface is not only hard and beautiful, but also slippery, smooth, sawing, long-term and long-term, long-life effect There is.
