Bakalaureusetöö peamiseks eesmärgiks on võrrelda erinevate koldematerjalide soojustehnilisi
ja füüsikalisi näitajaid. Täiendav eesmärk on uurida Eestis väljatöötatud uut koldeelementi.
Töös analüüsitakse koldematerjalide soojuspaisumist, soojusmahtuvust, survetugevust ja
tihedust. Statistiliselt leiti parameetrite vahelised seosed. Teema on aktuaalne, sest materjali
tehnilised omadused on olulised, võimaldamaks teha täpseid arvutusi, millele toetudes saab luua
efektiivsemaid ahjusid.
Suures plaanis jaotub töö kaheks osaks - teoreetiliseks ja eksperimentaalseks. Teoreetilises osas
analüüsitakse ahjude arengut ja materjalide kasutamist, tuginedes direktiividele ja erialasele
kirjandusele. Eksperimentaalne osa põhineb katsekehadega tehtud katsetel, mille tulemusena
leiti materjalide omadused. Töös kasutati voltmeetrit, ahju P330, digitaalset nihikut, ahju CPR,
elektroonilist kaalu ja hüdraulilist survestendi.
Bachelor's primary purpose is to compare the different materials of the furnace, and the physical characteristics in heat engineering. Another objective is to study a new furnace unit developed in Estonia. Study analyses the furnace materials, thermal expansion, heat capacity, compressibility and density. Statistical links were found between the material parameters. The subject is topical because of the technical characteristics of the material are important to enable to make precise calculations upon which more efficient stoves could be built. Study is divided into two parts - theoretical and experimental. Theoretical part analyses the development of the furnaces and the use of materials, on the basis of the directive and the relevant literature. The experimental part is based on tests with specimen, on which material properties were found. During the work, voltmeter, furnace P330, digital calliper, oven CPR, electronic weight and a hydraulic press were used.
